Solar (in)activity 16 Jun

[brianb]

Weather forecast was for a greyout but there was a useful sunny interval mid morning. Seeing was poor but, hey, it's better than no seeing at all!

The Sun is pretty quiet. Most of the large prominences seen recently have vanished, there is however an interesting filaprom on the SW limb.

0915 UT. Solarscope 60, 2.5x Powermate, DMK21. I had to make a composite as my camera has insufficient dynamic range to show the feature properly in a "one-shot".

There is an area of eruptive activity on the west limb, probably the last sign of AR 11081:

0918 UT. Solarscope 60, 2.5x Powermate, DMK21

The active region in the north eastern sector isn't doing much:

0913 UT. Solarscope 60, 2.5x Powermate, DMK21

0924 UT. Lunt 60mm, B1200 CaK diagonal, 2.5x Powermate, DMK21

Disk blank in white light.

CaK overview:

0904 UT. Coronado PST CaK, prime focus, DMK41

Ha overview:

0910 UT. Solarscope 60, 0.5x focal reducer, DMK41

Transparency good. Seeing poor with extensive boiling. Temperature 23C, wind N force 1-2.
