Another very cloudy day, overcast for most of it. Late on in the afternoon there was a brief break in the cloud so took the Solarscope out to do a quick sunspot count. |

Conditions were pretty bad (although not quite as bad as yesterday) but briefly clear enough that a view with the Solarscope was possible. Right away I could see active area 904. The main feature of the area was a very large spot that had a very dark umbra. Its penumbra was also very impressive with some detail in it visible — its outer edge also seemed to be quite dark and very well defined. Close by was a pair of very dark spots which appeared to be sharing a common penumbra. Both of them also had a very dark looking umbra. As well as the three big spots I could also make out three smaller spots close by. Because the area was so impressive I went inside to get a pencil and some paper so that I could make a sketch but, by the time I got back outside, the gap in the clouds had passed and there was no sign of another gap coming up. Also, because of this, I never got to try another naked-eye view. |
