              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear almost all night, but with variable seeing sometimes worse than 2 arcsec.  The telescope and instruments behaved well.
ARCSAT had a little trouble with something triggering the dome to close unpredictably with no error codes to show why; disconnecting the weather seemed to work, but it reconnected itself at some later point and the dome closed once again.  One pointing correction was also needed, but no reboot or major interventions.
