A Sun Event

17 May 2015 Sun - Compilation
17 May 2015 Sun – Compilation

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.

Clear sky to you all

Solar Serpent

Solar Filament & Prominence - 26 April 2015
Solar Filament & Prominence – 26 April 2015

Aloha!

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!

Evolution of a Solar Prominence

H-Alpha Sun - 28 April 2015
H-Alpha Sun – 28 April 2015

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.

Aloha,

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.

Partial Solar Eclipse - 20 March 2015

Hey ASOD!

I send you the great eclipse of the sun from Trondheim, Norway.
with 94% of the sun eclipsed!
I also measured the temperature (in shadow) before and during
the eclipse. The sky was clean until just before the end of the partial
phase. I enjoyed the max. partial phase very much. Beautiful!!!
I used crayons (watercolor) on black paper.

Best wishes from Per-Jonny Bremseth.

H-alpha Full Solar Disk – 8 February 2015

Aloha!

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.

Aloha!

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.

It’s the first time that I can see a spot naked-eye after a complete sun rotation. For the inverted watercolour shown here up, I use special glasses for eclipse, the orange color is this of my glasses, you can see some mist in the foreground meaning that the conditions were not perfect. For the telescope view I use a white light objective filter, I add an orange color layer after scanning.

Aloha!

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!

Clouds made it not easy to observe the enormous sunspot group AR 2192 in the Low Countries. I had only one good day to observe and sketch this marvel at ease. Thanks to good seeing conditions I could see – despite my small telescope – an impressive amount of detail. I hope the group will survive his voyage on the far side of the sun and give us another beautiful display.

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.

Spiraling Prom

Solar prominences including a spiraling prominence – October 12, 2014

Aloha!

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.

Two Big Prominences on the Edge

Two large solar prominences on the limb – October 4, 2014

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.

Kind regards,
Roel Weijenberg

Active regions AR 2171 and AR 2172 – September 27, 2014

Hello,

As soon as I put the eye in the ocular of the glasses, my heart skipped a beat(I saw red)! That the Solar surface is magnificently stained!

I decide to crunch(outline) one of the spots (who(which) I ignore N at the time of the drawing), the 2172, telling me that the task is already very sufficient(self-important) seen the scale of details.

Once ended, of small spots in small spots, I decide shyly to widen the frame(executive) in 2171.

The twilights of the main spots appear finely chiselled on their outlines when the turbulence calms down in a regular way.

Finally, at the end of 2 big hours of observation stuck on the ocular, and the aching loins, all the spots situated downward the Solar surface is there! I thought not at all of arriving there at this stage(stadium) from the first moments.

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 !

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.

Aloha!

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.

My place for looking at the sun
My place for looking at the sun

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.

Comments: Greetings everyone! Please allow me to bring you this new digital sketch utilizing my Iphone. recently or should I say last month- January. The Sun presented us with one of the biggest sunspots in recent times. That sunspot being AR 1944, It crossed the entire disc of the Sun from our point of view and went all around to reappear again. Well, here I’ve done my best to depict it as it is already under way racing across the face of the Sun. It is now designated AR 1967. It also comes with a fairly huge companion group – AR 1968. As some of you may already know, these freckles on the Sun are ‘cold’ areas comprised of strong magnetic fields capable of hurtling solar flares or coronal mass ejections, CME’s for short. As an added reference, I superimposed an image of the Earth just for size comparison next to those massive sunspots.
Back to the sketch! Are digital sketches or drawings considered a genuine art medium? A medium for sure but I once thought that maybe it’s a bit like cheating. Textures, colors, filters and a plethora of other effects are already predetermined and laid out for you. I’d say, If you get to show and display the view or scene that you have in mind using a digital format and you succeed, then it’s all worth it. I like the the ‘old school’ pad and pencils but i had to give it a try. Enjoy!

Dark and Clear skies,

Hi

This is a sketch of the biggest sunspot I´ve ever seen. It´s so amazing that can be drawn with small telescopes like the one I´ve used: the Astro-Professional ED80 equiped with binoviewer, a pair of 19 mm eyepieces and a 2.6x galsspath, that gives a magnification of 78x. I have used a Baader solar film to observe the sun with security. Although the seeing was not good at all, the view was great and unforgettable.

Best regards.

AR1575

H-Alpha / White Light Sun - September 22, 2012
H-Alpha / White Light Sun – September 22, 2012

Object Name Sun
Object Type Sunspot 1575 and crown
Location Néoules Provence France
Date 22 sept. 2012 – 13h TU
Media (graphite pencil for the spot, red pastel for the crown, two different white papers, Paint.net)

I made two separate sketches, one in H alpha via a classic PST for the crown, the second one through a 1000/102 refractor with solar continuum filter for the spot.
I used several eyepeaces.
The compilation was done with the freeware software : Paint.Net
Conditions were perfect, the sun was hot here… !

Clear sky to you all

Sketch created scope-side with white card stock, felt-tipped black artist pen, #2 graphite pencil.

Faculae were present in several areas around the limb, particularly around ARs 1473, 1469, 1474, 1475 and north of 1473 ~45 degrees. Sunspots were observed in all five active regions with 1474 ad 1475 only showing one per region. Seeing was poor and it was windy. I had to wait several moments to catch sharp views so may have missed out on pores in those areas. There were a few sunspots in the two active regions near the western limb, 1473 and 1469.

Active region 1471 was the area I concentrated for today’s sketch. The larger sunspot grouping was in the eastern region of that AR with very defined edges to the penumbrae and radial structure reaching to the umbrae. It was painstaking to wait for the winds to drop and seeing to settle to grab as much detail as I could. I dropped magnification and then increased when sky conditions permitted. That group appeared to have a chain of smaller sunspots, all sporting both umbrae and penumbrae leading east from the larger cluster of sunspots. A very faint speckled area was a further few degrees beyond the chain. I couldn’t make out if they were pores or simply penumbral blotches.

Moving to the western area of the AR ~10-20 degrees showed three more small groupings in that active region. The middle two of the AR had both umbra and penumbra and faint areas that looked penumbral to the south of them. The furthest grouping to the west was too soft and faint to be sure of its structure.
