Solar Prominences
Solar Prominences
Sketch and Details by Jeff Young

As the sun is finally attaining some altitude above the trees on my horizon, I decided it was time to wake my Solarscope up from its winter hibernation. There was quite a bit of surface activity on view, but I had neglected to bring out my sketching materials for disk work. No matter, there was a nice prominence complex as well, and I had everything I needed for it.

White Derwent Graphitint pencil on black Strathmore Artagain paper.
Sketched from County Louth, Ireland.
As viewed through 70mm Solarscope h-alpha filter, Tele Vue Pronto, Astro-Physics Barlow, Baader MkV binoviewer and 19mm Panoptics.

Cheers,
— Jeff.

DS 60mm Maxscope, LXD75, 21-7mm Zhumell
Sketches created scopeside with black Strathmore Artagain paper, white
Conte’ crayon and pencil, white Prang watercolor pencil.

Temp: 23.0°C-25.0°C , Humidity 52%-38%
Seeing: Wilson 4 dropping down to 2, Transparency: 4.5/6-3/6
Clear to scattered, light winds E changing to NE
Alt: 43.7 – 55.6, Az: 122.5 – 152.5
Observed inside observatory. Seeing became very poor as the inside
warmed up.

There looked like a possible new active region forming by bright plage ~
30° in from the eastern limb. There were several prominences scattered
around the disk, and the largest areas were on the SE and SW limbs,
changing dramatically over the course of the 1.5 hr observation.

Afternoon Prominences
Sketch and Details by Les Cowley

The sun lives! More out of hope than expectation I took an H-alpha look at the deep solar minimum sun with my Solarmax60 on the hot afternoon of August 19. Afternoons are usually a time of poor seeing, mornings before the ground and air has warmed are much better. Remarkably the image was steady and this complex prominence was evolving from minute to minute on the NW limb. Location. Sketch made at the eyepiece at 50X, 15 minute duration. Derwent Studio and Watercolour pencils on black paper.
