Object Name Sun
Object Type H alpha with PST, XW-10
Location Tokyo japan
Date 2014/9/28
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.
Thanks.

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.
I wish you all a nice and dark sky !

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.

I forget to say that :
In the foreground you can see two parabolic solar oven used to cook sausages and eggs for the public
A large prominence on Sun’s SE limb 1st June 2014. Hard to imagine that these glowing clouds are cooler hydrogen gas surrounded by hotter transparent plasma. Sketched at the eyepiece with Derwent Watercolour pencils on black paper. SolarMax60 H-Alpha ‘scope 50-80X. Location UK.

I was enjoying the Sun this morning and trying to decide how to represent the most prominent features. Sketching the Sun has just not gotten me the feeling that I can really represent it as well as I would like to as far as colorizing goes. I like using black paper but it isn’t smooth enough whereas plain white paper is. But when I have tried to add color later, it just loses what I see in the scope.
So today I tried a little something different. I like how some inverted blue colors really become the right colors for the Sun. So I put some oil pastel colors to paper & inverted to see what I could use. The nice thing about the oil pastel is I can scratch off small little lines to try to get the details of the solar surface. I had to think in negative to produce the sketch in order to preserve black, white and the different tones of red. This is my 1st attempt using this technique and I am not entirely happy with it but it is a bit of an experiment.

Since I exchanged Belgium for Sweden last year, I am faced with lack of astronomical darkness since mid april. Astronomical darkness (sun below 18 degrees of horizon) will only return end of august. Therefore I will be concentrating drawing more suns and moons instead of deepsky. The positive side to this is that in Winter time it ‘s astronomical dark at 5.30PM already 🙂
I have used my 21 years old TeleVue 101 SDF apochromate refractor, teamed with an (also old) Daystar 0.7Å h-alfa filter. A Barlow is needed to reach the required f/30 focal length. I am using a TeleVue alt-az Gibraltar mount.
I have added a picture to show the observation location. I have reached SQM 21.6 a number of times already.
Hope you like it.
best regards

From time to time, with friends, we animate minor scientific events in small Provencal villages.
Today March 19th we were in Varages with the local AAP astro club. Fifty kids and residents came to have a look at our star’s volatile proms in H-alpha and some nice spots archipelago’s in WL. We used 3 refractors, a Lunt 35mm a Coronado 60mm and a classical 102/1000 for the WL. The annexed sketch was done in H-alpha, directly on site, to show to the spectators, what can be seen through our material. In parallel some of our wife’s are trying to explain that our sun is a star.
Clear sky to you all !
