AR 2371

The sketches below depicts AR 2371 and were made on 20 and 21 June 2015 respectively. I used my 10″ SkyWatcher (with a solar filter and masked down to 100 mm) and a Baader Hyperion 17 mm eyepiece for 70x. At both occasions the seeing was rather bad, and the group didn’t show any finer detail. Inserted to the right are the corresponding images from the Solar Dynamics Observatory showing the group to the upper left.

Edit: I had the opportunity to do a third sketch today (inserted at the bottom). Equipment as above.
