Full Disc H-Alpha – April 22, 2013

H-Alpha Sun - April 22, 2013
H-Alpha Sun – April 22, 2013

Object Name: Sun
Object Type: Star
Location: Deventer, The Netherlands
Date: April 22, 2013
Media: White pastel pencil on black paper, colorized and mirror reversed with Photoshop

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.

Hello,

I send you my latest h-alpha-sundrawing from 23.01.2013. I send you the positive and the negative version of my drawing.

Object Name: Sun
Object Type: Star
Location: Freising-Lerchenfeld, Bavaria, Germany
Date: January 23, 2013
Media: graphite pencil, knife, digital tools (Minolta Dimage Z2 Camera)
Time: 13:45 – 15:00 MEZ

Telescope: Coronado PST (40/400mm)
Ocular: 9mm SW

I use a drawing pattern with lightgray sun. I draw the prominences, sunspots and filaments with graphite pencil. For the active regions and flares i use the knife to scrape the gray color off. On this away I can hold finest details.

You can find more of my sundrawings on my website: www.dersonnenzeichner.de

Mercury Transit – 1970

Mercury Transit
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!

Dear ASOD,

I send you my latest sketch of the Sun in H-alpa. I cought a very nice prominence which has already „departed” from the disk, and looked very interesting. It was not changing too much within the 20-30 minutes I observed it.

Date & Time: 7th September 2012, UT 10:20
Equipment used: Lunt LS35T H-alpha 35/400, 12mm & 7 mm eyepieces
Media: Graphite pencil used on white paper
Seeing: 8/10, transparency 5/5

Clear skies,
Judit

Two Days in the Life of Our Sun

H-Alpha Sun
H-Alpha Sun

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.
