I had around 40 minutes to sneak in a few shots today, the sky was overcast at sunrise, then a temporary clearing occurred around 9am. I rushed out and took this set. Right afterwards, the monsoon storm moved in and rain ceaselessly on us! While seeing was not great - around 2/5 - this set came out fairly well. We await a major sunspot group to return on Monday. Will it be once again awesome, or a ghost of its former self?
Halpha:
Lets start with the full disk for today. A bit lacking in solar activity, but not completely without spots:
Next, we take a look at the rim of the sun, and overexpose the disk to reveal the proms. The disk is then blackened out to avoid a big distraction!
Some very unusual proms indeed are here! Now back to the disk. Here Ive put in the 3x Klee Barlow which works quite well in Halpha to zoom in a few disk features:
And now the same setup, but over exposed once again to show the faint proms on the limb. Too bad the seeing was so bad, they look like they might have lots of details if the monsoon atmosphere would steady down a bit:
Finally, a special treat. This is the main group imaged in the Red Wing of Halpha. This is a side band, about 3/4 and Angstrom off toward the red end which clearly reveals the bright spots around the periphery of the sunspot. These are micro flares which last around 2 - 4 minutes each and pop on and off at high velocity which puts them via the Doppler effect at this shifted frequency. They are called "Ellerman Bombs".
