                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st shift: Russet McMillan
 Occasional clouds, mostly good seeing, and LOTS of Shack-Hartmann data.
 Observing Specialist, 2nd shift: Camron Hastings
 Some light clouds, so no throughput measurements. Worked on DIS slit
camera and cleaned up the #3 filter wheel so Dave Woods can look into
the filter rotation problem. Filled instruments and went home.
