Supergranulation Cells in CaK


My image of Sunspot AR3030, 3032 and 3039 shows some interesting features. Looking near the limb a bright structure is visible, called the chromospheric network. The image shows also some cells of the chromospheric network.

Herschel Objects book

Nice surprise yesterday from my collegue Walter which handed me over "The Complete Guide to the Herschel Objects". The book summarizes Sir William Herschek objects. It describes each of the 2435 objects the author filtered down based on errors from the original lists of between 2478 and 2511 objects.



As I'm working the Herschel 400 list, this book is a nice welcome and maybe a future challenge :)

My first observation of an Ellerman Bomb

 


When looking at my H-Alpha timelapse I noticed a bright white light popping up beside a filament. The time between between the two pictures is 10 minutes. I found out that this phenomen is known as a Ellerman Bomb or a micro solarflare.
This is the first time I observed and imaged this phenomen.
