              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS red ion pump was running at 1.1e-5 when I went to open the dome tonight.  It was fine at the end of the night.  I emailed Bill so he is aware.
Gmech focus offset for DIS works better at 32000 steps than 22000.
Still seeing small oscillations in the az error tonight.  I am also still seeing oscillations during the slews in az and errors in the +/- 40 range.  While checkking focus at the program change, the alt error was sitting at -2.5 and the current at -5, this caused the start kind of wanted to drift.  I slewed in Alt to fix to try to fix, but it persisted.  Hopefully the guider will keep things centered.  I noticed the alt current and errors were higher than normal tonight.
It's Miller time!  I saw 3 Miller moths in the control room tonight, UGH!!!   There were a few fluttering around the dome this morning as well.  :(
