Solar Imaging Session - September 11, 2014

The sky this morning is clear and seeing is not bad. AR12158 and 12157 Sunspot Groups are the groups to be monitored as they show very nice umbral and penumbral structures. Also, early this morning , Sunspot AR12158 erupted on Sept. 10th at 17:46 UT (Sept 11th 1:46am Philippine Time) producing an X1.6-class solar flare. I was only able to get some of the remnants of that flare this morning. There is a nice group of eruptive prominence that is visible in the SE limb but the rest of the solar limb in Ha is quiet. Numerous flares can still be seen specially on AR12157 Sunspot Group as well as AR12158 Sunspot Group. Overall, a nice solar imaging session as I was able also to do both white light full and high resolution and Ha images as well.
