              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
saw tooth on alt at 06:17 (00:17) and weird harmonic in Load cell T.
The night started out mostly clear and became clear.  We had good seeing all night.
ACP crashed and needed to be restarted but the ARCSAT computer did not need a reboot. I noticed a saw tooth pattern in the alt current at 00:17 (06:17 UT) but was not able to see it in the CSS plots
No problems tonight.
Remember y’all, tomorrow is Pi Day!  So get ready to whip our your flour and eggs or just your cell phone to reserve a pie at your local pie shop!
