              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Night began with heavy clouds and rain in the nearby area.  Apollo team
opted not to risk the weather and gave their time to CU02.  First drops of
rain on the site occured around 22:30 MT, accompanied by nearby lightning
strikes ~15km.  Second and third observers were not able to get on sky.
Third observer noticed that arc flats with DIS were wrong, the lines were
slanted about 45 degrees from vertical.  Ultimately homing the grating
turret, then returning to original settings did not seem to do anything.
 Reconfiguring the grating file seemed to work okay.  This is probably
related to on going issues with the DIS turret motor.
