Sun stuff 30th January

At last the sun is out and there is activity up there! A couple or three small flares on the edge and on the surface a really nice flare area has come round the edge of the sun. No spots but a couple of large wormlike filaments from near the flare which seem to slightly change shape as you watch. With luck (and if god don't pull the bedroom curtains) we will be able to watch this lot moving across the sun for a good few days. (The surface filaments are obviously not as large as sunspots as they don't show in the sun binos.)

We also tried to image the sun surface detail with a cheap TV camera through the scope but while it shows the flares on the edge it gives no surface detail on the settings we tried. We wonder if the camera doesn't work in the part of the hydrogen alpha band the surface detail is on so the glare of the rest blots out the detail. (On the TV screen the sun and flares show as orange rather than the red-orange the eye sees when using a normal eyepiece.)

It is 1st of February and we have the sort of sky that says snow showers but...

For just 5 minutes the clouds rolled away - or actually thinned down to a light filter strength - and that gave enough time (with a PST on horizon tripod) to dive out, set up and get 4 minutes of sun viewing before the thick curtains got pulled across.

The active area of two days ago is on the move with two (some would say three as one is @ ____) long very black worm-like filaments dragging along some way behind - a bit like the wake on a ship.

The @ ____ filament is not half as impressive as the lower arm at right angles to it. This one is like ____________ stretching for maybe a hundred thousand miles across the suns surface, like a thick black worm that is more or less straight. There is a couple of other areas of dark on the surface too so the sun does seem to be waking though (maybe due to the cloud filter) no flares were seen round the edge.

No time to try TV with filter to cut down light. (Thanks KK) and, as the wind picks up to howl we decamp indoors.
