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

Sun Super Spot – Unaided Eye

The naked eye view of the Sun through solar eclipse glasses and detailed view of AR 2214 through a refractor telescope with a white light filter - November 20, 2014

Object Name (Sun)
Object Type (Sun photosphere)
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 !

AR 2192 in Detail

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.

Hello,

Enormous sunspot AR2192 was one of the events lighthouse of these last days, so enormous as it was the object of several drawings of which this one, made on October 27th, 2014.

Four hours were necessary to realize it (2 hours behind the ocular + 2 hours to polish up it installed at a table).

Lunette of 102/1000 – ocular ES 6,7 mm – Prism Herchel and filter Continuum.

Department Yvelines – FRANCE.

Bye.

H-alpha Solar Observation

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

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.
