Object Name: AR 2192
Object Type: Sunspot group
Media: Graphite pencil on white paper. Digital work done with Gimp 2
Seeing was very good at the beginning of my observation – i was able to magnify 200x. The visible details were breathtaking and I decided to sketch just the most striking part of the sunspot.
I was also able to observe and sketch a nice X2-Flare.
This week has been fascinating observing the giant sunspot region 2192 making its way across the solar disc. I was working today to demonstrate the details of the intricate swirls of magnetic activity around the sunspot and filament regions. I utilized the Tilting Sun graphic again for this observation though it is reversed from a standard view to demonstrate my view through the eyepiece.

Tilting Sun graphics added in Photoscape
Todays Sun was bursting with excitement along the eastern limb. The more northern triple arch was very bright and dense in appearance. There was some activity near the equator that as I watched began to develop a bright spike. Then to the south, so beautiful and delicate in appearance, a spiral shape twisting off the limb. This was very exciting to sketch and time was spent creating and erasing to get it just right, trying to capture the spiraling effect.
I have been trying different techniques to capture the Sun recently. Graphite pencil on white paper is my current favorite method to get the smallest details my eye can see. A brush with charcoal was used to get the mottled surface of the solar disc.
Modeling after Erika Rix, I added a Tilting Sun graphic to show where the 2 major prominences were located on the solar disc.

Object Name: Sun
Object Type: Solar prominence
Location: Deventer, The Netherlands
Date: October 4, 2014
Media: pastel pencils on black paper
As the days shorten rapidly and the sun gets more south every day, the warm afternoons are coming to an end in the Netherlands. On what could be the last sunny and warm day of the year, the active Sun was the obvious target for an astronomical sketch. I set up my modded 60mm Unitron/Polarex refractor and sketched two large prominences on the western edge of the solar disk. The prominences were of the “stable” and relatively long lasting type, but still a lot of internal swirling and changes in brightness could be seen in both at high magnifications. Due to seeing conditions magnifications were limited to about 80x-100x. I made two separate sketches, but got the idea of combining them in a composition when photographing them afterwards.
Object Name Sun
Object Type H alpha with PST, XW-10
Location Tokyo japan
Media Black/red pencils on a white paper. Contrast adjusted with PC.
This my first submission to the site. I hope it is acceptable.
An M-class flare has erupterd at #2172 about one hour after this sketch. I could already see some active regions between the two sun spots.
Object Name (H alpha Sun )
Object Type (Nice dwarf star)
Location (Artignosc-sur-Verdon, France)
Date (2014/09 – 19 & 20)
Media (graphite pencil, white paper, my digital tool is Paint.net to add colours via layers)
What a bad weather! Even the “day of the night” becomes the “day of the rain”, what a season.
But here around we are not too complaining. For my cloudy friends, I made a couple of solar sketches to prove that the sun still exist !
Both sketches and zooms are done in 30 minutes, at 15:30 UT Sept. 19th and the day after, same period, with my mini-Lunt35T and SWA 10mm EP.
The prominences that rises are damn pretty and clustered around the equator as it should be at the end of a solar cycle.
While observing our ever changing Sun today I was struck by a grouping of prominences on the western limb. All of them of high intensity and curving towards the same direction. They made me think of the story of Goldilocks & The 3 Bears!

First International Sun-Day
· Object Name (International public event)
· Object Type (Sun)
· Location (Varages – Provence France)
· Date (2014 June 22)
· Media (graphite pencil for the sun, water ink and watercolour for the scenery, white paper, Paint.Net to assemble)
This first International sun-day was a good time to show the sun to the public, today in the north hemisphere the day is much longer than the night. The day before, the local radio broadcast make our promotion. With the local association “AAP” (Association – Astronomie – Provence) of Varages we had good time and very nice public. Despite the fact that the sun was quite calm, we can show a very tiny archipelago of sun-spots on the middle of the disk as well as some spots neat the limb. Anyway, the proms make our day; they are much more attractive for the public today.
To sketch the H-alpha part of the sun (here the portion out of the disk) I used a Coronado 60mm refractor with a focal length of 1000mm ; for the inner portion, the disk in Wight Light, I used my 102mm refractor, same focal length with glass objective filter.
