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

Location (Artignosc-sur-Verdon/France )
Date (2014/11/20)
Media (graphite pencil (sketrch down) and watercolor (full sun up) on white paper, Paint.net)
The old sunspot 2192 is now making its second pass across the face of our sun with a new number : 2214.
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.

Clear sky to you all !

Object Name: AR 2192
Object Type: Sunspot group
Location: Carinthia
Date: 2014-10-26
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.


Biggest sunspot group in 20 years

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.

Aloha!

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.

Active regions AR 2171 and AR 2172 - September 27, 2014
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.

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.

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.

Sun – White Light – February 4, 2014

Object : Star / Sun
Date : February 04, 2014
Time : 10:30LST / 03:30 UT
Location : Surprise Arizona USA
Medium : Digital sketch done on Iphone with apps
Instruments : Orion 25×100 Binos, William Optics GTF81 APO, 5mm Orion edge-on planetary eyepiece, White light filter, Iphone with PaintFX and Juxtaposer Apps.
Magnitude : -26.7
Weather : 65deg. F, Clear sky (in the morning), no wind and just great day altogether!

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,

Juanchin

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.

Active Region NOAA 11471

PCW Memorial Observatory, Texas – Erika Rix (www.pcwobservatory.com)
Temp: 34.4°C, winds S 9 mph, lightly scattered

2x Barlow, Thousand Oaks glass white light filter.

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.

Date : from 22 to 31 august 2013
Media : graphite pencil, white paper

Comments :
Dayly sketch of sun made through a small Coronado PST (H Alpha) + 15mm Televue eyepiece
Method :
1) dayly observing sun coronado around 12h TU
2) quick sketch with ballpen on paper notepad (2 minutes)
3) later copy out on drawing paper with graphite pencil (10 to 12 minutes)
4) picture take of each drawing with camera + Photoshop processing
– flipping horizontally and vertically in order to see the correct sun orientation
– grouping the 9 pictures + date on the same sheet
One may see the sun rotation from August 26 to 29 watching at spots.
I saw some material projections ejected into space (see August 30)
We currently have a great solar activity
To see the solar prominences evolution one should have to observe every hour !

Thank you for taking into consideration this small contribution

Hello to all,

Today we had a sunny morning, only the sky was crossed with light cirrus clouds. Why shouldn’t I look to the sun? The sun came up with some sunspot groups and an bright area (maybe flares?) on me. I could not help, I took the drawing pad an my pencil and start to draw. Maybe the sunspots in overview are little bigger than they real were, but I think the details outside the circle are located close to the original. Hope you like it too.

With sunny regards

Dear Asod,

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.

Equipments used: 114/900 SW (100x) & Lunt 35/400 H-alpha

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.

Mercury Transit

Hey Artists!

As the time of the “last” transit of Venus is perhaps ended, I would like to show all an old
but spectacular observation of a transit of Mercury I made in 1970.
My sketch shows not only a solartransit, but the planet also passed over a close bipolar
sunspots!!
It was interesting to observ the absolute black Mercury with the umbra in the spots.
The umbra was easy seen brighter. My info on sketch is in norwegian!
This was a lucky observation, indeed!!
Location : Trondheim, Norway.
I used pen and pencil on this original sketch.

Thanks for nice comments on my sketches!!
Have a clear sky and nice time to all!

Object Name : Sun
Object Type : H alpha observation
Location : Montreal, Canada
Date : September 2 and 3
Media : Acrylic on black paper
Scope: Lunt LS60THa/B600|CPT on motorized EQ3 mount.

Our star put up a great show during 2 days. I was able to observe the «good hair day» of the sun for a total of nearly 5 hours. Many proeminences, which remained relatively stable throughout 48 hours, could be seen. The observation of September 2nd was interesting. I started the observation around 13:00 EDT keeping the magnification low (25-50X) to sketch the whole disk and the distribution of the proeminences. I kept an eye on AR 1560, which was facing earth. Around 14:00 EDT this region began to light up. Two bright flares (showed at the upper center lane of the first disk) were clearly visible and increased in brightness for the next 30 minutes. Then they faded away and by 15:00 EDT the phenomenon ended. I was glad to be able to capture this activity on my sketch.

The sketches were done on black Pastel Paper with HB pencil to record details of the proeminences. The disk was traced with a compass. Acrylic paint (red and yellow) was then used to reproduce the color seen in H alpha. The paint was layered with large and small brushes directly on the lines of the HB pencil. The two separate sketches were photographed and then assembled with Photoshop CS3. No color or contrast adjustment were done except for the background.
