The spot in active area 953 was still visible but I could see that, since yesterday, it had spit into two with a large umbra and a small umbra both sharing a common penumbra.

Using a pair of eclipse shades I could also see that the spot was visible to the naked eye.

I took the following photograph of my view of area 953 with my Canon EOS 400D

Active Area 953

I could also see new active area 954 which contained two very small spots.
