              ------------- ACTIVITY LOG --------------
Observing Specialist: N.Ule
Observer used the R830 grating for DIS instead of the R1200.
Dust periodically caused problems, including a dome closure from 00:40 to
02:40.  Afterwards the dust and gusty winds kept the seeing poor for the
rest of the night.
