              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
Opened a little after sunset due to threatening clouds overhead moving away.
Again had problem with DIS slit viewer control click.  This time the mouse
did not show the control click symbol.
At 0121MT there was a motion error on alt. This was at an az/alt of
237.5/28.5.  I checked alt drive for moths but could not find any sign of
moths.  Multiple slews up and down where fine but there was drive
slippage.  Makes me think the drive ran over a moth and slipped until moth
debris spread and drive could regain traction.
