Solar Activity 06 Mar

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 :headbang:

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:

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)

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

And, just for completeness, the CaK disc overview:

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

Great shots Brian! and I've just managed to see the filaprom too. I haven't been out for a few days, but today has been good fun so far (Registax is chugging away as we speak).
