              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS Red HV was again found off during my afternoon checkout.  I restarted it.  Vacuum settled to around 2x10^-6 torr after about 25 mins.
I reset the NA2-rotator controller tonight (again).  I went up to zero the rotator during checkout, it looked a little off from the mark on the tape.  The rotator would not move when commanded via talk2boxes.  That let me to reset the NA2-rotator controller, which fixed the issue.  Rotator was found off by -0.140 deg.  I leveled it and reset it back to zero.
DIS red HV was fine at 04:30, when I did my end of night fills.
Clouds & Thunderstorms kept us closed all night.  My 2nd half observer gave up, due to weather, at 04:15 with completely cloudy skies.
