28.03.2020 Same prom. Another day.

*

Saturday 28th. 28-43F. Hard white overnight frost. 

10:30 Early mist has finally cleared to sunshine.

10.47 48/45F Thermal shaking and displacement of image. First processed capture of 10 o'clock prominence. 640x480 plus 2x WO Barlow for increased image scale. [Right]

278fps, 40% of 3k frames. 3.6ms with max Gain at 400. For over-exposure to show the prom clearly against the background.





11.44 51/47F The seeing is getting steadily worse! The prom has flattened on top and extends a more obvious chain of clouds towards the north.

12.35 50F. Lunch.

After lunch I was commandeered as the token domestic lumberjack to tidy up an overgrown hedge. It was well after 3pm before I could return to my solar imaging duties. Seeing conditions now absolutely awful with lots of cloud crossing as well.

I had left the drives running over lunch because it ALWAYS, ALWAYS stops when it passes the meridian. At least it does during a slew of any kind. Not today! I returned to find the telescope on the north side of the pier facing south west. No damage done but I shan't ever trust it again.

At least the date and time are keeping track now that I have replaced the button battery in the AWR IH2 paddle. One remaining oddity is CduC/Sky Chart's habit of turning east into west for the observatory site. It lost longitude altogether today. As soon as I reset the correct easterly figure it promptly changed it to west! Grr?

Pointed the telescope at the lovely, crescent moon. It promptly clouded over from the north and was never seen again!
