August 20, 2015: Lunchtime H-alpha sun: the eastern limb on fire!

[michael.h.f.wilkinson]

Just went out for a lunchtime H-alpha session with the students. The eastern limb is full of fire at the moment. Down south there is a huge pair of tree proms, just north of it a complex, bright prom consisting of several elongated structure floating above the limb, and northernmost there is a very long but low arc. Well worth a look. The surface is mostly quiet, except for the large AR in the southeast, and smaller AR and lone filament on the western half of the disk. Hopefully I can get most stuff done early, so I might have a go at imaging

The new large AR does look promising, nice to hear HA is still giving plenty of action.

I am starting to get a bit envious of all the rays you guys are receiving .... still complete cloud coverage here in Northants at the moment   I hope it continues for you
