Sunspot number 10656 was very large. It is almost certainly spot number 10649
coming round again. I was lucky enough to be able to image on most days as it
moved across the Sun. It is interesting to observe how its detail changed over time.
Compare with spot 10649, below. |

Sunspot number 10649 was very large. I only managed to image in on four days as it moved across
as it moved across the Sun between 14th and 24th July 2004. It is almost certainly the same spot as reappeared as 10656 on 6th August. |

These are spot groups 10634 (upper spot) and 10635 (the bigger group) imaged at a focal length of
about 630 mm (my ETX125 with a 0.33 focal reducer). This picture was taken on the 22nd June. |

And a closer view of Spot Group 635 also taken on 22nd June. |
