Eruptive Filament

Recommended Posts

Just managed a late afternoon observation and there was a very dark "U" shaped filament to the west of AR2061 at 1545 UT.  I thought it was a sunspot group at first as it was so dark!  Some plage in association and it looked like a candidate for a flare if it lifted, however no flare resulted.  By 1600 UT it was two parallel lines with the northernmost line fading quickly.  By 1606 UT only the southern line remained and was also fading fast.

I've just checked again 1621 UT and there's another dark filament formed in much the same place, smaller and more triangular if anyone has a scope set up, worth keeping an eye on.

1631 UT second filament fading, now just two short lines.
