24 hours ago, the sunspots groups 735 (below) and 736 (on top) were far from the Sun's limb. This shift proofs the Sun's rotation. Will they be still visible tomorrow when the Sun will rise? I don't think so.
Only one week ago, the group 735 didn't had yet reach the Sun's meridian... and the group 736 wasn't exist!
The inset seems to be darker than the solar disk of the background picture. This comes from the limb darkening: the Sun's limb is darker than the center, because of the Sun's atmopshere darkening more strongly the limb. |
