I was looking at the Sun Now page on the Solar Dynamics Observatory site. Sometimes that page shows wonderful energetic explosions on the solar limb but it may be too cloudy for observing.
Sometimes the solar action can be enticing enough to set up the PST (Personal Solar Telescope) and sketch when the weather permits.
March 30th Easter Saturday was one such day. When I looked through my telescope there was a long twisting filament. Interesting north limb prominences challenged my eye as they altered their shapes over time.
When observing the sun you do not see the movement right in front of your eye. The sun is 149,600,000 km away from Earth and it takes eight minutes for its light to get to us. The observation of movement is perceived over 15 to 20 minutes and can lead to very useful sequences of drawings. In one way it’s like real time natural stop motion animation. Because my solar telescope is small the enormous solar disc (Diameter 1.39 million km) appears to be less than the 40mm diameter of the telescope. The filaments, active regions, sunspots and prominences are very tiny to the eye. A sunspot or prominence can be many times the size of the Earth but only millimetres to the eye. When I draw I look really really closely at the shapes, and textures of these features.
I pay great attention to the negative spaces, the black spaces between the multiple strands of plasma gas that are launched into space by the suns continuous activity.
Before I draw I observed the action for a while before deciding on an approach. It is difficult to draw filaments as they appear to the eye on the solar disc. Filaments can be very dark against the bright sun or very grey almost like stringy cobwebs. Filaments are eruptions of electrified plasma gas; they seem dark as they are cooler than the sun that created them. When a filament continues its action over the edge of the solar disc it is called a prominence. More structural detail within these features can be seen against the blackness of space. When a filament is seen to swing its action from the solar disc around the limb is it known as a filaprom.
For this drawing I used an etching method for the filaments, the combination of etching and drawing seems to give the desired effect for the moment.

Turn Left at Orion signed for the school library
St Cronans National School Bray had a very special visitor on Wednesday March 20. None other than the Vatican Astronomer Br Guy Consolmagno SJ. Originally I had invited him to drop in and shake hands with St Cronans Stargazers our astronomy club, but he very generously offered to give a talk for the whole school. 500 boys and their teachers were treated to a wonderfully pitched talk about the Vatican Observatory, the pope’s interest in the subject, the wonders of astronomy and all things that give joy in the vast universe in which we live.
The boys asked very intelligent questions, Br Guy gave them a listening ear, his answers inspired and intrigued the entire audience. Br Guy Consolmagno SJ is an American research astronomer and planetary scientist at the Vatican Observatory. He presented Principal Maeve Tierney with a signed copy of his famous book Turn Left at Orion for the school library.
Br Guy was delighted to visit Bray, after lunch in the Martello and a walk on the prom he dipped his hands in the Irish Sea, a rare moment for him in his busy global speaking schedule. I first met Br Guy back in 2005 at the Whirlpool Star Party, at the time I had no clue who he was but we had a warm conversation about binoculars and observing. I was invited to this premier event to give a talk about Enceladus ( one of Saturn’s ice moons) and found out next day that Guy was there to deliver a talk about Turn Left at Orion. We met up again during International Year of Astronomy 2009. Br Guy was on a speaking tour in Ireland. The first of his talks was at the Dublin Institute of Advanced Studies and Dunsink Observatory, followed by Gonzaga College. We then continued on to COSMOS (Now - Irelands leading Star Party) in Tullamore and then to Blackrock Castle Observatory in Cork. If my memory serves me right, Guy delivered six different talks in five days to varying audiences everyone of them a polished gem in communicating the science and wonder of astronomy.

Deirdre Kelleghan – Ireland Feb 18th 2013
The objects from my childhood that are still in my learning zone today are black paper and chalk. I was bored as a child in primary school, the only thing I really enjoyed was drawing. Simple drawings with white and coloured chalk in a small black papered book. The drawings were separated by tissue paper with strong indented patterns.
Today drawing complex images of the sun and the moon is one of the most poignant joys of my life. I use black paper and pastels. Pastels are sophisticated chalk and I have a thing about black paper, which is never quite black enough for me. I use my blackest black pastel to make it so. I draw to learn and understand, it is something I have done all my life, to draw is to know.
I am an old fashioned Astronomical Sketcher; it was big before astro photography. My drawings are like photographs and are very accurate. I know this because I can put a photograph of a solar image or lunar image taken at the same time beside my work and my drawing is accurate to a high degree. I take the sun and moon from the sky via my telescopes with my eyes and chalk and put them on black paper. This activity is soul filling and I love it. I teach astronomy through the medium of drawing and artistic activities and am never bored.
Almost Full Moon Lunation 12.75 days Sketch
Get the Moon in your head
‘At conjunction the moon occupies a position between the sun and the earth; it is then illuminated by the sun’s rays on the side which is turned away from the earth. The other hemisphere, which faces the earth, is covered with darkness; hence the moon does not illuminate the surface of the earth at all. Next departing gradually from the sun, the moon comes to be lighted partly upon the side it turns toward us, and its whitish horns, still very thin, illuminate the earth with a faint light. The sun’s illumination of the moon increasing now as the moon approaches first quarter, a reflection of that light to the earth also increases. Soon the splendour on the moon extends to a semicircle, and our nights grow brighter; at length the entire visible face of the moon is irradiated by the suns resplendent rays, and at full moon the whole surface of the earth shines in a flood of moon light. Now the moon, waning, sends us her beams more weakly, and the earth is less strongly lighted; at length the moon returns to conjunction with the sun, and black night covers the earth.’
Extract from Sidereus Nuncius (The Starry Messenger) 1610 by Galileo Galilei translation by Stillman Drake from the book Discoveries and Opinions of Galileo.
Now there ye have it, direct and clear from the master Galileo. Read it slowly, imagine it, and animate it in your mind. Observe it for yourself, spend time with the moon soon you will understand its movements.
Galileo was a great man for sharing the moon through his telescope. He shared with other scientists, princes, students, the pope, and artists. He was compelled to share it as it was such a magnificent sight even in his small telescope. He wrote Starry Messenger to share his drawings and observations of the moon, far and wide.
The way Galileo writes about the moon pulls you in to be part of his exploration. He thereby transports his readers to share his thoughts as he figures out the lunar surface, phases and features of the moon observed over 400 years ago. Today you can still find freshness pouring from his enquiring mind in his descriptive writing.
Sharing the moon with the public is an affliction borne with large smiles by many astronomers all over this planet. It’s amazing that there are so many people today that have never had an up close and personal view of the moon in a telescope. International observe the moon night invites astronomers to show the moon to people on September 22nd. This is a global event, with an increasing bubble of participants.
If you have binoculars or a telescope consider joining in and showing the moon to your neighbours. Register here its easy.
Check the map for other IFAS clubs sharing the moon on the night
The moon is a constant in our existence; our eyes are drawn by it to look up from all over the planet. Galileo made sense of the moon for us, at great risk to his freedom. Neil Armstrong and Buzz Aldrin lifted the entire planet by landing on it for the first time back in 1969. On September 22nd you can easily pick out the Sea of Tranquillity with your eyes. Wink at the moon is an action request from Neil Armstrong’s family, to honour his memory. It’s also a really cool simple public outreach exercise.
Weather permitting I will be on the promenade near Bray head with St Cronan’s Stargazers and our telescopes from 19:00 hrs till 20:30 approx September 22nd
What's up for September 2012 from Jane Houston Jones
On holidays in Waterville Co Kerry I had some luck with solar observing during this rainy winter of a summer. July 19th my first view of the solar disc in days presented me with what looked like a loop within a loop C shaped layered prom on the eastern limb. Oh that had to be sketched it looked unusual.
PST 40 @50X 10:15 U T it seemed to come from a slight depression on the limb.
I never got the chance to observe the big Active Region 1520 but suspected this might be a goodbye wave :-) I like to be accurate in drawing solar features so I can compare my drawings to images taken at more or less the same time. This does two things A) Its feedback on the my accuracy and B) I learn from others who imaged the feature in order to further understand what is going on in my observation. On this occasion my sketch was of a Coronal Loop. Magnetic looped prominences like this often occur after a large explosion on the sun, such was the case in my observation that morning. This powerful activity continued for something like twelve hours.
Image of the loop by Dave Tyler included in the slideshow below.
Once again on July 26th I had the happy chance of observing an enormous twisting prom on the NE limb. Never seen anything like it before, it was a veritable cornucopia of plasma gas swirling from the apparent edge of the sun. The rest of the disc had very busy filaments jumping and twisting like ropes .
I am continually working on techniques to sketch filaments, active regions, flares, and proms. The challenge of capturing the sun on paper is in my opinion one of the most difficult gauntlets to satisfy in astronomical drawing.
WOW !! this is huge in the hall
St Pauls Senior Girls National School in Greenhill’s Dublin 12 is just a few minutes’ walk from the house where I grew up. It was fortuitous to have the opportunity to carry out my third Action Sun for a school in this area.
On June 25th 47 young girls from third class, took part in building the sun. This was a very positive group all eager to get going and get busy. Streamers of orange and red paper flew through the air in vast amounts. In a short time the photosphere began to grow in the schools courtyard.
The activity of Action Sun supports the school curriculum in its art as it uses mixed media to create the sun. The program uses paint and paper to convey activity and explosive movement on the solar disc. Action Sun also supports primary school art as it enables children to use the characteristics of the materials to make structures and features on the solar disc. Making the sun in this way is both creative and explorative. Learning a little science through the arts facilitates the use of many kinds of intelligences. The learning process in the making is as valuable as the finished suns. Textures and spatial organisation also comes into the creation of this work. The girls at St Pauls School were very good at working as a group, helping each other out. They also made good decisions during the activity which showed they were an excellent team. This is kinesthetic learning, learning by doing.
Action Sun compliments science in the primary school curriculum on several levels. A short information talk in between making the suns features informs the children about our suns role in the solar system. We talk about the scale of the sun and the Earth. We talk about the energy of the sun and its function in relation to the other planets. The mini talks make sure that the children understand that the sun is our main source of heat and light. By building the sun the children learn by hands on investigation. The children literally explore the physical features of the sun with their hands in mini scale. A quick review of the evaluation sheets shows the quality of the learning. Several children not only drew sketches of the complex sun but also put in arrows to the different features and labelled them all correctly. The action of throwing the paper was very popular, signing their names was also a highlight and for some children carrying the sun into the hall was the stand out moment of the day.
When I look at the sun in my solar telescope I see a huge amount of detail and very often in the past I have shared that view with children. However it takes a long time to show this view to a large group as the sun presents as a small disc with tiny features. It is difficult for children to comprehend the enormous scale of our nearest star. I put Action Sun together to bridge that gap and help more people achieve some understanding of this wonderful star in safety with a big fun element.
The features of the sun itself were totally new to this young group, but at the end of the programme words like photosphere, chromosphere, filaments, prominences and sunspots were all a little more familiar. We closed our eyes at the end of the build and held our faces up to the sun to feel its heat and remind ourselves that it takes eight minutes for its light to get to us here on Earth, a 93 million mile smile. Building the sun took about 90 minutes. The 7.9 X 4.9 meter tarpaulin was pre prepared at home using four litres of matte black masonry paint. During the activity we used approx 3,500 individual pre cut pieces of crepe paper ,15 litres of washable PVA glue, 6 litres of yellow paint , 1 litre of red paint, plus the energy of forty seven eight and nine year old third class girls.
My thanks to Sarah Jayne Reid for setting up Action Sun at St Pauls and to Phil Curran for all her efforts prior to, during and post the build. Thanks to Ms Keating, Ms Daly and Principal Sr Maureen for their support during the activity. NASA Sun Earth Day bookmarks, posters and other educational material were provided to the teachers. The solar feature data for this Action Sun was an observation of the disc made from my PST earlier that morning. The Solar Dynamics Observatory website was pointed out to the girls so they could continue to watch the sun safely.
What's Up for July 2012 from Jane Houston Jones
As I approached the City of Kilkenny medieval towers and spires broke the dull May skyline. Pure yellow rapeseed fields painted sunshine on the landscape. Rich green wheat moved slowly in the cold breeze each side of the motorway.
At Kilkenny Castle on National Drawing Day my Action Sun participants were young families randomly stopping by and taking part for short periods. Small children throwing crepe paper photosphere clumps with smiles on their tiny faces. Just as well for the completion of the project that two boys Max Gronowski aged 12 and Daragh Lynch aged 12 got stuck into it from the start. They helped paint the acrylic / glue base, the root for two of the suns atmospheres. As the solar build progressed my information spiel became simply a three and a half hour conversation with the boys. They asked questions, I answered; we discussed the photosphere as we threw our orange paint dipped paper targeting the empty spaces on this sixteen foot highly textured sun. They asked ‘where did the sun come from’? What will happen to the sun in the future? How big is the sun? They could not wait to fill in the photosphere and move on to apply the chromosphere. We talked about solar telescopes, space telescopes, the dangers of looking at the sun, the Venus Transit, Apollo 11, becoming an astronaut, Mars, going to Mars, Mars Science Laboratory, photosynthesis, energy and light. At that point Action sun had become a constructive dialogue with two very tenacious boys. Some parents came to help for a while and we were joined for the last hour or so by Matthew Shortall aged 9 who helped to make our photosphere denser which on a solar disc of that diameter was a very big task. Daragh said it would be great if we had music to work by, ‘what kind of music?’ I asked, Beethoven was the unexpected reply.
We had dragged the sun through the clouds and reproduced it on the ground. Groups of adults got answers to ‘what’s going on here? Is that the sun? ‘Ha ha I have not seen that for weeks’. ‘Does it really look like that?’ ‘What are the black things?’
Max helped place the sunspots using my drawing made directly from the Solar Dynamics Observatory website at 09:02 IST. We made the filaments, I added the prominences; local papers took photographs of the creation. The sun never showed its face at Kilkenny Castle that day but as each hour went by the sun on Earth was growing brighter every minute as our build continued.
Venus, a black polystyrene ball on the end of a stick, demonstrated the transit as seen from Ireland against the newly created sun. The Earth had escaped from my car earlier and spent the day in the middle of my driveway.
We actually ran out of time, our photosphere big as it became, was just not dense enough and the boys knew it. Our red thinly spaced solar chromospheric paper fluttered in the wind. Sticky hands and paint splattered tee shirts told the story of almost four hours of creative work.
For their wonderful effort I gave the boys NASA Sun Earth Day packs. They helped me give out Venus Transit information to all who passed by. Max, Darragh and Matthew signed their names proudly to the giant canvas as they had done most of the work. The 7.9 X 4.9 meter Action Sun will hang at Dunsink Observatory during Solarfest on June 23rd. The photosphere will be complete by then.
Action Sun first light was with St Cronans Stargazers children’s school club on May 4th 2012. Sixteen boys and I constructed an eight foot solar disc based on my early morning observations. This eager group worked on the sun interspaced by pockets of solar information delivered in short bursts which punctuated the action. Link to blog
Action Sun was funded by Dublin City of Science 2012 and The Butler Gallery Kilkenny Castle , Kilkenny City. Action Sun was a NASA Sun Earth Day event alsoAction Sun – is an indoor or outdoor activity which allows groups of children to participate in building a large solar disc or several solar discs. This Earth built sun mimics the photosphere and chromosphere of the sun, includes sunspots, filaments, and prominences present on the sun ideally in real time. The materials are simple, paper, glue and paint. It is kinaesthetic participatory learning for young children. The activity educates and supports science through art and the creative process.

On May 4th 2012 children from St Cronans Stargazers Astronomy Club in Bray took the sun from the sky and brought it down to Earth. We used a 10ft X 8ft plastic sheet, crepe paper, acrylic paint washable glue and plenty of energy. It was a very cloudy day but a brief look at the sun in the early am gave me a good view of the large sunspot in Active Region 1471. I took the rest of the data from the space telescope Nasa Solar Dynamics Observatory. ‘The sun now’ on its website shows the status of the sun in many light views in real time.
By building the sun the children were literally exploring the physical features of the sun with their hands in mini scale.
Exploring astronomy via art is a very varied learning for all participants. Even finding out a little about what we see in the sky during our entire lifetimes is enhancing for life. Understanding where we are helps us understand who we are.
Art expressing unique awe and wonder at the magnificence of our stars role, in every second of every day of our lives is unavoidably beautiful.
Astronomy and Art are for everyone, each person has something to express, each has their own life journey to make, to live, to experience. The action of bringing the Sun to the ground, bringing it down to Earth is a deep experience that can only have a positive effect. Action Sun invites children to be creative, expressive, and informed.
During the activity I emphasised to the children the dangers of looking at the sun. Action Sun is a very safe way of exploring our star in a way that enhances a child’s knowledge and encourages curiosity and further learning.
During the making of our sun in Bray we had just finished the photosphere when spontaneously some of the children bowed down to the paper sun. This was a funny happy moment, so totally unexpected, it came out of nowhere. When we were carrying the finished sun into the school, the smallest child began singing ‘here comes the sun’ I was amazed that a 2012 child would know that song and even more surprised that he sang away. The singing soon became a group effort as we struggled through the double doors into the hall.
Action Sun supports Art in the curriculum as it uses mixed media to create the sun. We used paint and paper to convey action ,and explosive movement on the solar disc. Action Sun enables children to use the characteristics of the materials to make the structures and features on the solar disc. Making the sun in this way is both creative and explorative.
Making is the technological component of the Science Curriculum. Action Sun provides the child with an opportunity to make the sun, and thereby investigate its properties in their school yard.
Action Sun is a cooperative activity encouraging social skills and group learning. The goal is to bring the sun to Earth to examine it and observe it safely. We were not just aiming for an understanding of the subject matter but were making connections between head, hand and heart while cultivating the capacity to discover systems. Observation and wonder equals sustained learning.
Action Sun supports Geography in primary education as the Solar System is part of the lesson plans. The Sun is the central hub of our solar system and is therefore one of the most important objects in our daily lives.When the Action Sun piece was hung in the hall , the children said ' the suns up , the suns up' with smiling faces, what a happy moment.Action Sun was created by Deirdre Kelleghan slide show below

Whats up for May 2012 from Jane Houston Jones
Windmill in central Leiden
‘'The Rhine is one of the longest rivers in Europe' this long lost primary school fact popped into my head as I ate my delicious Goats Cheese, Nuts and Honey Salad. I was sitting on the deck surrounding my hotel in Leiden, watching Dutch families enjoying the waterway. Their Sunday picnics were neatly arranged onboard, as they glided along in the welcome sunshine.
When I arrived in Amsterdam some hours earlier I admired the fact that the train station was in the airport and then the bus station was in the train station in Leiden. This was joined up thinking and so was the week ahead of me.
Professor George Miley and Pedro Russo had invited me to come to Leiden University to take part in a UNAWE workshop and series of talks with other like minded individuals. It turned out to be a very eclectic mix of outreach educators all with a common affiliation too UNAWE or AWB or both. In the invited group of 59 individuals there was 26 countries represented. It was inspiring to be part of such an erudite gathering of minds and intentions.
I was particularly pleased to be asked to give a PechaKucha 20X20 presentation about my new activity for children called Action Sun. This Art/ Science activity is designed to bring the sun to Earth in real time using paper paint and energy.
A PenchaKucha talk is 20 slides with 20 seconds to speak about each slide. The slides change automatically so you have to stick to the subject and get your points across in double quick time. Twelve other PenchaKucha's followed mine from a wonderful bunch of presenters. 2. Jaya Ramchandani (India): Universe in a box
3. Grace Kimble (UK): Evaluation
4. Angela Perez (Colombia): Astronomy Clubs for Children
5. Claudio Paulo (Mozambique): Astronomy education in Mozambique
6. Cristina Olivotto (Italy/Netherlands): Space Camps for Children
7. Catalina Movileanu (Romania): UNAWE Romania
8. Premysl Velek (Belgium): Scientix
9. Eric Chisholm (Canada): Astronomy & Art projects for Children
10. Avivah Yamany Ryadi (Indonesia): Transit of Venus 2012 and Children
11. Thilina Heenatigala (Sri Lanka): UNAWE Sri Lanka
12. Mponda Sibuor (France ) Astronomy in Tanzania 13. Carla Natário (Portugal/ Netherlands): Transit of Venus 2012 UNAWE Project Timor-Leste
To my delight Action Sun was very well received and I hope it will be part of Dublin City of Science 2012 shortly.
The activity I have created helps groups of children to understand the sun and some of its features safely without the need for viewing the solar disc visually. I have developed both an outdoor and indoor version all of which will be extremely colourful and I hope satisfying to the children who will take part in it over the next few months.
It was an honour to hear talks given by scientists and educators who had a wealth of experience over many years in outreach. It was a joy to meet several people who were only known to me via e mail and with whom I had engaged on interesting astronomical projects. One of the most useful activities of the week for me was talking part in the evaluation working groups and meeting up with some people who were very adept at that aspect of outreach education. One of the most uplifting experiences was seeing the vast numbers of children and young people being touched by astronomy in many ways. Professor Mark Baileys Human Orrery in Armagh , Olayinka Fagbemiro (Nigeria) with her enormous smiling childrens group in Africa. Marcello Souza's fun energetic outreach in Brazil , Mponda Sibuor beautiful work in Tanzania all stick in my mind. It was also amazing to listen to Maria Luchetti tell her story of twenty years doing creative but very practical astronomy outreach teacher training at the Rosa Sansat teacher training facility. (via translator Rosa Ros (Barcelona, Spain)
Before I left the University I recorded a piece to camera for Brazilain TV via Marcelo de Oliveira Souza and a piece to camera for 365 Days of Astronomy for UNAWE via Jaya Ramchandani . The entire experience gave me new eyes to look at both myself and others. It gave me a huge respect for outreach education being carried on in Africa and other countries with many difficulties in their everyday lives. The group attending the workshop week were collectively delighted when Professor George Miley founder of UNAWE was presented with The Order of the Lion (the Netherlands highest honour) at the official opening of the talks at the old observatory in Leiden.
