Mostly overcast day but had a brief clear spell so took the Solarscope out to do a quick sunspot count.

The single spot in active area 923 was still huge and impressive. The umbra appeared to have developed a slight "pinch" in the middle that made it appear like it could split into two at some point soon. The penumbra was still very strong and obvious.

The spot was still easily visible with the naked eye using eclipse shades.

I could also see three small spots in the newly visible active area 924.
