Comments: 

1.5m Coating Area Light was ON. Thanks to Javier Rojas who got the key to that area and turned OFF that light.

DIMM2 down at 02:53 UT. Back around 4 UT down again at 4:45 UT. Up and down! Relative Humidity 45% to 75% and at after 3UT down to 60%. No DIMM data last quarter of night.

Limit problems with HD 109510B, unreachable, moved to other objects so to make time. Ended last object with Sun at - 10.2 degrres Altitude.

Thin clouds... or smoke of Australian wildfires? Visible looking North West thanks to Moonlight.

I thought PC Guider Camera 2000 pc was not in use? It shows high activity of its hard drive (LED light blinking.)
