Solar H-Alpha – AR11057
Sketch and Details by Erika Rix
*2010 March 26, 2033 UT.
Solar h-alpha, AR11057.
PCW Memorial Observatory, Zanesville, Ohio USA – Erika Rix.
DS 60mm Maxscope, LXD75, 21-7mm Zhumell.
H-alpha sketch created scopeside with black Canson paper, white Conte’ crayon and pencil, white Prang watercolor pencil, Derwent charcoal pencil, black oil pencil.
SW prominence at first glance looked detached. Increasing mag and waiting for steady seeing, I could make out fainter portions of the prominence that reached the limb. There were a few brighter prominence regions scattered about, but nothing of great significance, especially after the magnificent NW prominence last week.
AR 11057 stood out immediately with two dark areas and bright plage. Panning the FOV brought out another bright plage area on the WNW area just 10 deg in from limb. This could possibly be a remnant of 11056. Toward the southern-middle of the disk, brighter little clusters of plage scattered the area, as well a plage to the NW about 40 deg in from the limb. There were a few filaments but the one that really caught my eye was a wide V-shaped one to the SE. I had to tweak the Etalons to bring out the full structure of what first appeared as a single line of filament.
Erika,
An excellent observation of the solar disk showing AR 1057 and several prominences. Thank you for sharing it with us all.

Erika,
Always a pleasure to see your super solar sketches in H alpha.

Incredible way to draw, for me of course, I like the 3D efect it give to me.
Wonderful!

Very impressive, for second I thought I was looking at a photograph.
