                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
AZ velocity scale measured 572.9 was 580.0 changed 573.0
Alt velocity scale measured -637.6 was -636.0 changed -637.0
02:58:35UT Dump of Altitude looked strange.  We only had readings for the magna sensor at 59 deg
even though we have been on the sky for a while. Fiege 110 star field didn't look correct but
pointing check looked fine.  Turned out the bright object was the planet Uranus, with several
moons visible.  Fiege110 was the "dimmer" star in the field near the boresight.
We had bad pointing at changeover, due to a bad magnasensor crossing.  I slewed the telescope in
Alt to clear the error and that fixed the problem.
Relatively poor seeing all night, but not as bad as last nights.
DIS blue ion pump running high this morning (again).
