FD's and AR12712

Post by krakatoa1883 »

AR12712 is now of B class (although it is still officially labeled as a C group), I couldn't observe any defined penumbra around the main spot, however this morning I observed 18 spots in the 80mm scope, most very small. In WL there is no much else to see and the disc is almost entirely blank, but in Calcium light the bright plage around the active region is really prominent.

Today I have not been able to get rid of the LS50 sweet spot, this scope's behavior is sometimes erratic.

Lovely shots. AR12712 shows considerable evolution since I imaged it yesterday.
