                ------------- ACTIVITY LOG --------------
1st Half Observing Specialist: Camron Hastings
We did not open due to heavy cloud cover until 23:58. All worked fine
when we did though.
2nd Half Observing Specialist: Russet McMillan
The clouds thickened again and PU01 was unable to get anything useful
after 02:00.  The NM02 program, which included brighter targets, had
more success.  We had one failure of the GRIM application, but
otherwise everything went smoothly.
                   ****** OBSERVER COMMENTS ******
X. Fan (PU01):
Struggling with clouds; some useful data collected.
