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!

I went out to sketch the AR 2339 in h-alpha but when I saw this massive Hedgerow type prominence on the limb it had to be done.

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.

Webmaster’s note: ASOD is experiencing problems with sketch submissions where the file size exceeds the limit of the ASOD WordPress programs capability to process the file. Please be aware that when this occurs, although we do have some graphic editing programs, large files will result in two or three iterations of resizing, that may still result in a sketch that cannot be downloaded to the ASOD template. Due to the fact that I have a day job, I often put these pages together late at night, and being very tired I have difficulty trying to bring these posts together. Please be aware that we would prefer receiving files that are no bigger than 800 pixels wide. We will always resize your sketch image to 650 pixels to fit on all the the standard protocols for tablets and smart phones. Please make sure the image file size (the number of bytes the image file) contains does not exceed 500 Kilobytes. This will guarantee that your sketch is published in it’s entirety, and on time. If there are any questions, please feel free to contact us here at ASOD, we will be happy to help with any problems that are troubling you with image size issues.

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!
