H-Alpha Sun – January 23, 2013

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

Kind regards,

Michael Wendl

Hi all! I present to You a sketch made by a 9yo child, Her name is Wiktoria Janowska. I met Her at the Zelow Observatory a couple days ago. She’s very, very clever n lovely little woman. Well, sometimes her fantasy dominated over realism. She saw a lot of details, maybe a little too much 😀
I hope You like it 🙂

Monster Prominence

Solar Prominence - July 27, 2012

Object Name: Prominence
Object Type: Large plasma eruption on the solar surface
Location: Deventer, The Netherlands
Date: July 27, 2012
Media: White pastel pencil on black paper

This morning I aimed my 70mm solar telescope at the sun and I almost got blown away by what I saw. I GIANT prominence on the north eastern limb. I hovered above the surface like a huge dragon. I made a sketch with white pastels on black paper, color added and orientation-flip with Photoshop.

Clear skies!

The Sun of november the 7th

H-Alpha Sun - November 7, 2012
H-Alpha Sun - November 7, 2012

Object Name (Sun)
Object Type (H alpha regio…)
Location (Rocbaron in Provence – France)
Date (2012 Nov 7th)
Media (graphite pencil for the prominences, pastel on white paper for the solar texture, Paint.net as digital tool)
Scope My new Lunt LS35THa/B600 on motorized EQ3 mount with 10mm eyepiece.

I made a pastel texture on CàGrain Canson white paper to imitate the solar surface, and I sketched the proeminences on another paper with graphite pencil. Then I combine both digitalized sketches via Paint.net respecting the 3 bright areas. I cheat a little bit regarding the color pushing my sketch to orange which is maybe more convenient for the contrasts.

Clear sky to you 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.
