Hi.

Good stability is gone. Back to med to poor conditions.

I'm always starting my sketch detuned to draw the sunspots first in white light. On this one,on the first look, there was a very dark filament in inverted M shape right to the main sunspots. After consulting GONG website, I assisted to a very fast surface flare. After completing drawing the sunspots and this filament I returned to h-alpha view and the filament was gone and no more visible.

I got only very few of that kind of dark filament only visible in white light. Very special view.

Andre.
