30.12.19 Solar?

 *

Monday 30th 42F some intermittent sunshine appearing at 10.30 after a false start, earlier this morning. When more low cloud arrived. Sun very low and the sky is still full of fast moving, low cloud. Probably a waste of time trying to do any imaging. Gong Ha shows a white smudge in the southern hemisphere but little in the way of proms.

Pm. 14.00 45F. Sky cleared but a strong, gusty, southerly wind blowing straight into the dome and moving the telescopes around. The house chimney is totally eclipsing the sun! Sawed off the motor support bracket to clear the helical focuser. Needs still more metal to be removed but the motor tuning is still working. Quite a sharp image until the chimney intervened. 6" H-alpha objective is slightly steamed up inside.

14:20 Now the sun has cleared the chimney but the telescopes are shaking. Strong, thermal wave agitation of the disk and limb. Just when things could not get any worse, low cloud is scudding across. Fps dropped from 280 [800x600] to about 75fps. Captured a couple of 1000 frame videos but they were shortened by cloud crossing the sun.

4:25 Sky rapidly becoming completely obscured with low, racing cloud from the SW. Disk just visible through the cloud to the naked eye without discomfort. I might as well find something more constructive to do.
