              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Again tonight the telescope did not want to move in alt/az on the initial slews.  It took 2 power cyycles, with the stop button, and then small slews, in each axis separately, to coax the telescope to move.  Once it moved, the axis was fine.  These were not motion errors but normal buffer empty and it just didn't slew when commanded by the tcc. I did see the aztime and alttime warnings in the tcc log window.  Not sure when they cleared (I assume after the 2nd stop button cycle).
Clouds closed us at 22:26  We re-opened at 23:45
