I viewed the Sun with the welder's glass and I could see a sunspot! It must be big, I thought.
Fired up the Questar with the solar filter. Saw 5 groups of sunspots, including a very small pair near centre. I roughly sketched it.
I correlated the spots to images on spaceweather.com and SDO. They labelled everything except the small pair.
