Our friends of the La Blaque observatory in Varages had organized an afternoon dedicated to solar observation. We were ten of us behind the eyepieces to admire the hot sun rays.
Here join a small overview of the animation (the base color comes from the coffee offered by Caroline)
We deploy heavy EQ, Celestrons (the famous Hats of AiryLab) some large Lunts a Skywatcher and other solar bino’s. I had a lot of work at the sketch board !!! Only a 150 mm Lunt was devoted to the photography.
Here is a little souvenir from the H-alpha compiled views from the Fred’s Hat, the 150/1200 for WL and a nice Jean-Luc bino for 3D view…
As the sun had become much quieter than previous days, it was not particularly complex to draw today, but we do what we can with the star we have! On the left we can see the active area around the end of the AR2339 spot.
I was delighted this morning to find this dark and large filament at the north-eastern limb of our Sun. It had the appearance of a large serpent with foot like projections anchoring it to the solar surface and then visible curving around the limb. The filament is magnetic curtains of plasma hovering over the Sun’s surface, this an especially large and detailed one. I read on the Spaceweather site that the length of the filament would measure the distance from the Earth to the Moon. That’s one big serpent!

On April 28th, I had the opportunity to follow the evolution of this very nice and long prominence.
That was made using a very small Lunt in Halpha (35mm) the total sketch time was less than 2h.
The full view sketch was made using black pencils HB and 4B on white paper and with the help of transparent paper for the active zones, inverted while scanning.
For the sun’s “comic” I sketch only on white paper with a HB pencil, I had no time to sketch more details and the other details were quite calm facing the prom evolution.
This kind of exercise is interesting because no space probe, nor camera are programmed or able to send us such a big number of photo’s and so quick. Let’s say this is another evidence why sketch is still an interesting technique, as is ASOD !.
The filament, origin of this prom is visible on the main sketch and on the first one of the sequence, after that the filament disappear. At the end I just add a digital color layer to my sketch with the use of Paint.net.
Thank you to you all for your interest and on top of that thank you to the ASOD team for their work.
Todays solar surface showed some interesting features that I tried to capture. There were a lot of long detailed filaments as well as a region to the east that looked like a piece of silk that had been crinkled and then flattened. To the west of this area was a brightening plage, at the moment the brightest region in the observation besides a bright spike on the limb. The prominences to the north were more subtle and dim.

SUPER SOLAR FILAMENT: It is, arguably, the second biggest thing in the solar system. A filament of magnetism almost 1,000,000 km long is stretching across the face of the sun. Only the sun itself is bigger. Stretched out, the line would fit 67 Earths!
The Suns surface has been very interesting to follow the past few days. A fascinating solar filament stretching across the surface is one of the longest recorded, over 700,000 km long. Solar filaments are made up of unstable plasma held above the solar surface by the Sun’s magnetic field.
I was able to observe it for 2 days in a row and marvelled over its sheer size, looking like a tear in the Suns surface. On this day there was also an interesting filament like region near the west limb that was wide and appeared dimensional in light and dark values. The “wishbone” prominence to the north appeared to be from beyond where the limb was visible, the top portion reaching toward the observer.

I think what I like best about solar observing is you never know what you will find going on! This large prominence at the eastern limb appeared extraordinary in its detailed and lacey appearance. Seeing was very good and at higher magnification a network of bright areas appeared, much like a picture of a neuron cell with branching filaments extending in all directions. Tilting Sun Graphics are used to denote prominence location.

Another Sunday morning spent happily with the Sun. Today the first prominence that struck me was one that had the appearance of a very fine “tree” near a “bridge”. The details & seeing were excellent today and I could make out swirling and looping details within the prominence, a lacy network of light and dark. The prominence could be seen spilling onto the solar surface as a filament.
I usually just cant leave done alone, so I tried some different things to colorize and experimented with Photoscape software. I fell upon the magic button – something called color balance. What fun to add color and see more of what I observed in the eyepiece!

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.

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.

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.

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.

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.
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.

My technique is quite original, after a light circle portion made by a graphite pencil on white paper I use directly a pure watercolour “green emerald” to sketch the solar surface on a water base and then the protuberances on the dry part of the sky, taking into account that light green will become dark red and vice-versa. Then I just have to invert the colours after scanning. The white sky is becoming black while the green part is becoming “H alpha red”.
Right, I add the approximate dimension of the earth and the moon orbit.

NOAA 11543 had very bright plage. The sunspots within it weren’t quite as pronounced as the other day. There was a very large filament going east to west in the SE quadrant of the solar disk. More plage located to the SW and the E-NE quadrants.
The brightest, largest prominence that I spotted was located on the NW limb and resembled two dancers joined by their outreached hands with their other hands stretched out behind them. More prominences were scattered about the limb, but to the SW, a very short, bright set of prominences were apparent.
I send you hereby my sketch made this Saturday at Polaris Observatory, Hungary. I used a 114/900 Skywatcher with Baader solar filter for white light sketch and a Lunt 35 for the H-alpha sketch.
The most intersting part is a solar prominence on the northern edge, which is was a very 3D something, biting in the sun-disk.

Sunny weather + long lunch break = solar observing!
This afternoon I took 30 minutes to sketch the Sun in h-alpha. It’s been so long since my last solar sketch, I even had to search for the pastels. I made a full disk sketch, the active region AR1726 was large enough so see in detail even at low magnifications. For this sketch I used a 22mm LVW (32x) in my 70mm h-alpha telescope.
Please find attached one of my latest sketches made of the Sun with my Luns LS35 H-Alpha telescope.
We had a lot of cloudy days so far this year, with only a few opportunities to go out and do any kind of observations, but finally the sun was shining and obviously I was sketching! J
