Solar Activity 14 May

[brianb]

Unsettled weather overnight cleared during the morning. The Sun however is very quiet, completely blank in white light & very nearly so in CaK:

0934 UT. Coronado PST CaK, prime focus, DMK41

Just for a change I made a close up of the centre of the disk to show what the quiet Sun looks like in CaK:

1020 UT. Lunt 60mm, B1200 CaK doagonal, x2 barlow, DMK21

There are no bright plage areas visible in Ha either. However the large complex of filaments in the north / north west persists, there is also a notable filament near the west limb; and a number of prominences scattered round the limb; all this is best illustrated by an "overview" shot (composite of limb & disc images):

1007 UT. Solarscope 60, prime focus, DMK41

This shows everything there is to see, apart from a faint group of prominences on the SW limb:

0949 UT. Solarscope 60, x2 barlow, DMK21

There are closeup images of the NW disc filaments and the other prominences in my Photobucket album for today.

Transparency very good. Seeing moderate with significant boiling. Temperature 14C, wind NW force 2-3.
