 Observing Specialist: G.Saurage
In the afternoon tcc was not responding and had to be rebooted. First slew after
coming back up worked then the second slew failed with this error: 23:48:47
APO.gabrelle 87 KeyDispatcher f Timeout; Actor='tcc'; Cmd='track 10.4450833,
-33.6522778 FK5=2000/Name="LTT377"/RotAngle=0/RotType=Object' Subsequent test slews
gave "Last fiducial error too large" for Alt a few slews. Cleared after many large
slews.
Mostly clear skies all night. Good seeing
