              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
High humidity at the beginning of the night.  I tried to work on
characterization of the new B1000 grating but had some trouble with one of
the  grating motors - fortunately not the most popular one.  Once I was
able to open I did some more tests of the new guide software and checked
collimation using SPIcam.
Second half was peaceful and productive with somehat variable seeing.
