Update 23:30 UTC:
The filament lift off we see here on the image to the left was maybe a result of a channel eruption
Right after that filament lift off we could see a rly nice explosion (ejecta) also seen on Stereo Ahead EUVI imagery

The CME looks really bright. Due to the location of the source (southwest) a direct hit will be probably unlikely. But a portion of it could strife us
