              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
03:18UT  Motion error too large in Az, while tracking
03:42UT  Az having problems tracking, Motion error too large error.
I did MS.DUMPS of the Az axis after doing a few slews after each error.  Recovery was to just restart the drives and do a couple slews.
No Problems after these two events.
07:30UT  Fire alarm (Teleco line) went down.  We also lost our connection to the outside world via the internet.  Luckily my observer had 2 long exposures going.
Internet came back in about 20 mins.  No observing time loss.
