                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: Camron Hastings
 All ran smoothly. Jeff Morgan logged in from UW to perform focus vs.
 temp tests. Skies were clear, winds moderate.
 2nd Half Observing Specialist: Russet McMillan
 Jeff continued his focus tests during second half, and I also tried
 some tests of various planetary pointing methods.  We didn't do
 throughput measurements because it wasn't photometric after midnight.
 I got an improved echelle pointing model to check some oddities I
 noticed in the last model, which was rather small.
