Brighter day today with lots of sunshine but unfortunately rather a lot of thin high cloud, patchy in nature, very obviously derived from persistent contrails from eastbound transatlantic jets which are constantly passing over.

Solar disc featureless in white light. Somone must have bought a white light filter  :mad:

Not much in the way of prominences either. The most significant proms are on the north east limb, where one is wrapped into a long thick "filaprom". Other thin filaments are snaking around the large area of low grade activity in the north east sector of the solar disc. There is also a thick short filament near the south pole, which doesn't show up well in my Ha overview shot:

2010 Mar 06, 1119 UT. Solarscope 60 @ f/5, DMK41.

ARs 1052 & 1053 have gone round the corner, and AR 1051 has decayed into a filament & is approaching the west limb:

2010 Mar 06, 1124 UT. Solarscope 60 @ f/16, DMK 21.

But the main interest is the north eastern sector, which I was able to "one shot" with my larger chip camera (tried to do this yesterday when the filaprom was even better, but the cloud beat me)

2010 Mar 06, 1130 UT. Solarscope 60 @ f/16, DMK41.

Here's a closeup of the north eastern activity in CaK

2010 Mar 06, 1140 UT. 60mm Lunt CaK @ f/25, DMK41.

And, just for completeness, the CaK disc overview:

2010 Mar 06, 1110 UT. PST CaK @ f/10, DMK41.

Transparency poor to moderate, milky high cloud derived from contrails. Seeing moderate to poor. Temp +11C, wind NW force 2-3.

Very, very nice shots Brian!  Been cloudy all day for me, though just clearing now at sunset.  I'm going to chance seeing and setup the C8 in a bit with a view to some visuals and images of Mars and saturn.  Tomorrow promises to be clear blue skies under this high pressure so planning a mammoth solar session all day.  Wink

Excellent Brian!, keep those stunning images coming in, I hope you get extra reward soon in the form on new large active regions.

Best of luck mark.
