                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
    I opened under mostly clear skies tonight, only a bit of cirrus. All
systems operated well. The new DIS slit viewer behaving well, more
sensitive. No need for darks up to 120 secs, although they help just
slightly at that exposure value. Count on about 120 seconds to identify a
20th magnitude object, roughly.
    DIS collimators are wandering again already for some reason. Today
RED is still in focus, very well, but BLUE has wandered a bit. I will
take a look at them again tomorrow if possible.
    Princeton's Mac failed for some reason and would not restart. I began
taking the images that they needed from here, which was easy because they
were long exposures. We did not lose any observing time.
 Observing Specialist, 2nd Shift: Russet McMillan
 The time originally scheduled for NM08 was given to NM04 instead, by
 request of the observers.  The GRIM observations went very smoothly
 under clear skies with sub-arcsecond seeing.
