AR2665 Returns (8-2-17)!

AR2665 has returned and is likely to be renamed AR2670. It appears to be significantly decayed from its huge self during its first transit. This image was taken between clouds in poor seeing. Note the plages (bright spots) surrounding AR2665 in this image. Plages are magnetic features in the photosphere associated with sun spots.

Imaged with ETX 90  and Mallicam DS 2.3+. Stacked in autostakkert with wavelets in Registax. 150 of 300 frames stacked.
