A blog about a system to determine terrestrial albedo by earthshine observations. Feasible thanks to sheer determination.

Observing logPosted by Peter Thejll Feb 26, 2012 10:42AM
Trying to observe M41. Temperature in dome 6.4 C at start. Very light haze.

Shutter giving problems: So far, all shots are bias frames - except one that is 0's in one third ... as if the camera died?

At one point, when this happened, some LabView panels having to do with Andor configuration and Shutdown moved to the front on the logmein display: I think this means they had been activated - I had done nothing to cause this - so perhaps it means that the system did it having sensed something was wrong?

Abandoned M41 - then tried the hohlraum source. No images at all recorded now.

Rebooted everything.
