Two Days of Incredible Solar Activity

H-Alpha Sun - November 12 and 14, 2011
H-Alpha Sun - November 12 and 14, 2011

Object type – Huge filament and prominence
Location – Wilp, The Netherlands
Date – November 12 and November 14, 2011
Media – Pastel pencil on black paper, color with Photoshop

The largest prominence and the largest filament I have ever seen, both visible at the same time! It was a fantastic view and I made two sketches of them, two days apart. On November 14, the huge filament blew a large part of itself away from the Sun at the exact moment I was observing, creating a thin candle-like flame above the surface. A remarkable sight. Clearly the Sun is getting more active every month. What it’s got left in its suprise box while creeping towards solar maximum? Can’t wait to find out!

Kind Regards,
