The Sun on 10.19.2014
It was not a good day for imaging, with lots of hazy cloud that significantly reduced image contrast. The sun continues to be very active. The following images show AR2192, which has been torching off X-Class flares (the most powerful flares the sun emits), and also filaments around ARs 2193 and 2187.
