              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I didn't take IOL data at the start of the night since Echelle was the first program on and Annie was taking cals.
The students arrived on site around 19:30 tonight.
ARCSAT camera hung while exposing tonight.  My user noted the library support error.  I rebooted the ARCSAT user computer to clear things up.  It seemed like it took an excessive amount of time to reboot this time, around 8 mins for the reboot and to bring the system back online.
No problems tonight reading in the focus log.
No 3.5m telescope issues.
