Slightly breezy day with lots of broken cloud but with the occasional period where the Sun could be seen. Took the Solarscope outside to do a quick sunspot count.

With the Solarscope I could see what appeared to be two active areas (875 and 876). Between them I counted 14 sunspots.

Of the two areas 875 appeared to be the most developed with what appeared to be two main spots, both surrounded by (and apparently joined by) extensive penumbra and a curved tail of smaller spots (surrounded by darker areas that didn't look like a penumbra).

Using eclipse shades I was able to see the main spot in area 875, as a small black dot, with the naked eye.
