                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st shift: Russet McMillan
 First half was characterized by persistent cirrus and good seeing.
 Observations for PU05 were hampered by the clouds and the target's
 high airmass.  GRIM observations using the instrument's polarimetry
 capabilities were also made more difficult by the changing cloud
 cover, but otherwise proceeded smoothly with few equipment problems.
 Observing Specialist, 2nd shift: Noel Camron Hastings
 The second half started OK, except for the thick cirrus. We closed
 early due to the opacity. Second half project did identify some
 targets though, which made the night successful all in all.
