                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 1st half was clouded out by a big storm front just to our East.  It finally started to move
eastward around 03:00 and we opened around 03:20.
10:24UT Az/Alt -115/46.7 a odd buzz on the intercom and a square looking wave on the az
current/error dataq plots.  The noise lasted until we slewed to the next object.  This didn't
sound like the 1Khz we normally hear at certain positions.
No other problems tonight.
