My first observation of a CME

As said in a previous blogpost I had a sunny but windy morning which made observing via PC screen very difficult. I was tracking the C6 solar flare near AR3372 (see my blogpost) when I saw another solar flare and dark plasma flying away from the sunspot AR3363. It's showing dark due to the fact the plasma is relatively cool and dense and so it silhouetted the glow of the underlying sun. It's my first observation of a live CME.

This solar flare is classified as a B7 (see info via this link).



Setting: SolarMaxIII d70/400 f/5.7 with reducer x0.5 and ASI290MM
Lights: 1000 frames (20% used) and use of flats
Software: SharpCap4, AS3!, AstroSurface Urania U4 and CS4
