              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The Red 300 gratings spectra seemed tilted tonight during checkout.  I re-homed the turret and gratings. It also was a royal pain to calibrate the Bay 2 gratings tonight, even after homing.  They seemed a little more vertical after two homes.  See dtest.0004r and dtest.0009r for comparison.
I went to calibrate the Bay 1 gratings and I got no spectra at all (either camera).  Ugh!  Detent was 728 now.  I changed to grating set 2 and then the turret got lost (blank).  I could select from drop down still.  I homed just the turret again. Detent 727, Homed again, Detent 1492. I got a spectra, WooHoo! PR Submitted
Humidity closed us at 04:10.  We never re-opened.
