26.11.2020 AR2785 & 6

 *

Thursday 26th 50/46F, early cloud clearing to sunny periods. Fast moving cloud from the west. 

AR2786 is spectacular. With 2785 dwarfed and almost insignificant. 

11.20 Promising but needs the etalon re-tuning to even out the lighting. Too much thermal boiling to allow the 2x GPC.

11.35 53/46F Still low cloud drifting across the sun.

Changed to 2x GPC as the seeing steadied a little. A narrow bridge is extending southwards across AR2786.

11.44 The bridge appears forked.

Sun only at 13° altitude. The image on the monitor is boiling and going in and out of focus.

12.13  Struggling to keep the forked light bridge visible without losing detail in surroundings.

12.24 White light image. Rotated to correct inverted orientation.

The new PSU has reach 63F in the airflow with the fan running.
