First day without cloud/ wind etc.
Managed a set of CaK with the Vixen 90M.


The current activity is impressive, some six numbered AR's visible:eyepop:
The Raben map shows them all.


AR 2887 is very photogenic! A prominent sunspot with umbra/ penumbra and a "family" of smaller spots and faculae following behind.
The new AR 2891 in the north looks very promising.
All it all a great time for solar observers.

Very cool set. You can see the black spot depression on the limb shot. :thumbsup:

A great set of Ca K images and descriptions Ken. The only remaining problem is with the weather. Full on thunder storms here today.
