Quiet Sun
The earth facing part of the sun is currently quiet. Active regions 1126 and 1127 are not active sources of flares. However, on the far side of the sun, there are a number of active regions (5 or so), so there's something to look forward to. Skies continue obstinately cloudy here in Indiana, so I've been unable to do any imaging.
