Object Type: H-alpha prominence
Location: Deventer, The Netherland
Date: July 15, 2011
Media: Graphite pencil on white paper
On July 15, I made the first sketch through my new 70mm h-alpha solar telescope. The scope showed a lot of detail, but a large prominence on the northwest limb was the most stunning feature. It was large, wide, and it changed shape within minutes. I made two sketches, one at 12.00UT and one 20 minutes later, at 12.20UT. The prom clearly changed shape an structure a bit and the base was much wider. It looked as if the prominence was falling back to the sun!
I sketched with graphite pencil on white paper, inverted the sketch and pulled all the levels to “red”) with Photoshop.
