                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
AzVeloScale: (no change)
AltVeloScale: (no change)
After sunset clouds increasingly became a problem until we were completely socked in
after 22:00. Closed at 22:22 with no break in sight on the satellite. Radar activity
and high dust levels second half.
In the brief time we were open, NA2 guider images seemed too dark. Cooler temp was
not set at -25. Set temps, restarted nubs and power-cycled gmech and eventually the
guider images looked normal again.
The big flat screen weather monitor may be showing symptoms of going out. It
flickered black a few times, not related to the screen saver, and would come back
stretched or flattened for a moment and then fix itself. I'm not sure the problem is
the monitor or the signal it's receiving from the mac.
