              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We did not open tonight due to weather.
Closed dome tasks done tonight:
I took an exposure with DIS for internal focus check. Russet examined and said the top/bottom were out of focus, meaning chip is tilted but center is fairly well focused. We will leave things as they are.
Kosmos internal cal exp times (for reference when Bill changes the ND filter)
New exp values to match the online plots
Blue Low
Ne - 60s (max counts around 7000 compared to 180k cts in the online plot (2s)).  Spectra is usable.
Kr - 360s (about half the brightness of the online with the two bright Littrow lines present, marginally useable)
Ar - 600s (very low counts and two 6000ct Littrow lines?, not really usable)
Qrtz - 60s (10K peak), 180s (25k peak)
Red High
Ne - 50s
Kr - 10s
Ar - 30s
Qrtz - 12s (1.25E5 peak)
I checked out ARCSAT software tonight (could not test on sky due to weather). I cannot connect to arcsat-tcs which is causing issues with the software on arcsat-user.
I gave up at 03:30 with a radar return of rain heading at us.

     The convention used is north=0 degrees, east=90 degrees.
     The dust count is particles > 1u per 0.1 cubic feet.
