               ------------- ACTIVITY LOG --------------
 Observing Specialists: R.McMillan
 Lovely photometric night with nice seeing (which I didn't really
 measure very carefully, but I know it was good).  I adjusted the
 pointing (tertiary tilts) for the echelle port, updated some PRs,
 nailed the instrument block for CorMASS (probably the best it has
 ever been!), and did some pickup science observations in the guise
 of testing out CorMASS, echelle, and DIS.
 I also played with the Shack-Hartmann for a while, tuning tracking,
 adjusting the tertiary tilts for the port, and getting a nice
 altitude sweep.
 DIS red side warmed up during first half and then cooled by itself;
 possibly there may be something wrong with the cryotiger
 compressor.  Unfortunately, it wasn't quite settled down when I
 wanted to repeat my throughput observations at lower airmass, so
 I'll hope to get another shot at throughput in the coming nights.
