              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Closed for the first half due to clouds, we opened for 2nd half but we still had clouds to fight.
During my test slews I noticed that the AZ error was much larger than I am used to.  Values +/-40 instead of +/-10 range.  I did multiple slews in AZ to see if this would get smaller but it didn't seem to.  Telescope seemed to slew ok (not on sky to check pointing) and I didn't hear anything unusual on the intercom.  I did multiple magna sensor dumps (~06:45UT) when I was trying multiple slews in Az to see if I could reduce the errors.  Moths???  Pointing was fine on the sky.
