Sunspots 17th Jan 2022

17th Jan. Lots of sunspot groups today. These active regions (AR) are numbered. Single exposure taken thru a WO 81 mm refractor with herschel wedge and Canon 550d camera. North is up, west to right. Thanks for viewing.

This is a really interesting shot compared with yesterday's images John. The newly named singular spot AR2933 has grown into an expanding grouping. Thanks for posting.
