Comments: 

Pretty decent night all in all -- the first 90-minutes we remained close because of high-ish humidity and quite a thick bankof cloud menacing us. However, even though there may have been some thin cirrus about (hard to tell beause the bright Milky Way is now setting in the West and RASICAM is not operational), we were observing throughout the remainder of the time.

 

Please put some de-caffeinated coffee in the kitchen (third time I've asked).
