Bringing the Sun to Earth

13:00 – 14:03 UT
May 4th 2012

May 4th 2012 14:03 UT Crepe Paper, Acrylic Paint, Washable Glue, Structure Gel and energy. Today in Bray Co Wicklow Ireland 16 boys from St Cronans National School brought the sun to Earth. Deirdre did some observations early in the day, but then because of cloud we took the rest of the information from ‘ the sun now’ on SDO. We added in Active Region 1471,with the large sunspot , some small filaments and some prominences. ( a bit of artistic licence there) We looked at the Earth to scale, we learnt about the Photosphere and the Chromosphere . We learnt about the Venus Transit. The event was part of Dublin City of Science 2012. The children did a great job and were very proud of their work. We carried our sun into the school singing ‘here comes the sun’ The Sun will be on exhibit for all the pupils to see and learn. The boys were members of St Cronans Stargazers the kids astronomy group based at the school. Action Sun – Lets bring the Sun to Earth by Deirdre Kelleghan Action 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 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. We made the Sun on Earth and also learnt about the Venus Transit

Solar h-alpha, Prominences – May 3, 2012

2012 05 03, 1845 UT – 2130 UT.
Solar h-alpha, Prominences and NOAAs 1469, 1471, 1472, 1473, 1474.

PCW Memorial Observatory, Texas – Erika Rix,
Temp: 33°C, winds SE 7 mph, occasional light cirrus,
Seeing: Wilson 2-3, Transparency: 4/6, 50x,
DS 60mm Maxscope, LXD75, Baader Planetarium Hyperion 8-24mm Mark III .

Sketch created scope-side with black Strathmore Artagain paper, white Conte’ crayon and pencil, Derwent charcoal pencil, black oil pencil.

With five active regions, the Sun made quite an appearance today in spite of the limb. There were a few decent prominences, especially to the eastern hemisphere. My favorite view, though, were magnetic fields surrounding 1471 made apparent by the very thin active region filaments (ARFs). They reached down like fingers from the sunspots in that region. Plage was very intricate and meshed into what I believe was AR 1472.

The quiet region filaments (QRFs) were in abundance in the southern northern hemisphere with a few speckled to the south. AR 1474 seemed a bit washed out with plage and faint darkened areas. There was only slight plage definition and no sunspots observed in h-alpha. I didn’t set up a white light filter today for comparison.

1473 and 1469 were blended together by the plage and many lines of ARFs, including filaments reaching out over the edge for short, bright prominences. Plage was very bright, forming the shape of a tuning fork in 1469. These were impressive sets of active regions when paired up.

This was my first solar observing session since moving to Texas about two and a half weeks ago. With all that took place in preparing the old house for sale and the move to Texas, I’ve been deprived of any observing other than naked eye. It was a relief to be behind an eyepiece once again.

H-Alpha Sun – April 6, 2012

Dear Asod,

I send you here my first sketch made with my L35ST Lunt H-alpha
telescope (not the first one with h-alpha telescopes tho).
I used 57x and 80x zoom for sketching.
The most interesting part was this very long filament, which was there
for 3 days constantly and almost in the same size.
The red-orange parts are showing the lighter areas.

Time & Date: 6th April 2012, UT: 9:30 – 10:00
Media: Graphite and colour pencil used on white paper.
Equipment: 35/400 Lunt H-alpha telescope on EQ2 mount.
Place: Budapest, Hungary

Solar Prominences

– Location: Lith, the Netherlands
– Date: 22-3-2012
– Media: pencil sketch on white paper & PS CS5

Today was a beautiful day. The sky was clear, the birds were singing and the sun was shining bright.
I decided to take a look at our star with the Coronado P.S.T. There were not so many sunspots visible, but the prominences were very spectacular.
When looking through the telescope, three huge ‘flares’ were visible at the right side of the sun.

Thanks for watching!

H-Alpha Sun – November 27, 2011

Hello,

i send you my latest h-alpha-sundrawing from 27.11.2011. I send you the positiv and the negativ
version of my drawing.

Object Name: Sun
Object Type: Star
Location: Freising-Lerchenfeld, Bavaria, Germany
Date: November 27, 2011
Media: graphite pencil, knife, digital tools (Minolta Dimage Z2 Camera)
Time: 10:50 – 13:15 MEZ

Telescope: Coronado PST (40/400mm)
Ocular: 9mm SW

My webside: www.dersonnenzeichner.de

I use a drawing pattern with lightgray sun. I draw the prominences, sunspots and
filaments with graphite pencil. For the active regions and flares i use the knife to
scrape the gray color off. On this away I can hold finest details.

Kind regards,

Michael Wendl

Two Days of Incredible Solar Activity

Object type – Huge filament and prominence
Location – Wilp, The Netherlands
Date – November 12 and November 14, 2011
Media – Pastel pencil on black paper, color with Photoshop

The largest prominence and the largest filament I have ever seen, both visible at the same time! It was a fantastic view and I made two sketches of them, two days apart. On November 14, the huge filament blew a large part of itself away from the Sun at the exact moment I was observing, creating a thin candle-like flame above the surface. A remarkable sight. Clearly the Sun is getting more active every month. What it’s got left in its suprise box while creeping towards solar maximum? Can’t wait to find out!

Massive Solar Prominence

Our star continues to provide stunning sights as we approach solar maximum. This huge prominence, among the biggest I’ve ever seen, is visible in the hydrogen alpha wavelength, but it takes a specially designed scope or filter to see it. My 40mm Personal Solar Telescope (PST) is one such scope.

The prominence consists of superheated solar plasma suspended along magnetic field lines. It is not static, but changes constantly–sometimes the changes happen quickly and sometimes slowly. The appearance of this prominence had changed subtly by the end time of the sketch, so if you want to draw one of these monsters, be prepared to work fast!
