                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 AZ Velocity Measured 583.5, did not change
 01:53:30 NIFPS folks filled up the hard drive on hven and knocked
 everybody off TUI.  PR submitted
 20:10 closed due to wind and humidity, we also has some light snowflakes
 flying around for a while.  We never re-opened due to wind.
 We had several power drops tonight, usually less than a second before the
 power came back.  My guess was due to the wind.
