              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Once again I opened late because of questionable weather.  Engineering tonight was mostly focused on DIS.  The blue spectrograph has a lot of contamination, but the red side is looking quite good.  I brought the slitviewer into better agreement with the red spectrograph about where the telescope focus should be.
APOLLO observed the three Apollo reflectors, starting with the one left behind by Apollo 11, in celebration of the 50th anniversary.  I also used the APOLLO guide video for some analysis of tracking stability.
