1st Half Observing Specialist: Karen Gloria
	The telescope was opened at 16:00 MST.  I observed for PU01,
unfortunately through some cirrus.  Dan Zucker observed for UW07, this
time DIS.  He's observed his target with all of the APO instruments
except for the Echelle.  No problems during his run except for some
cirrus and high airmass towards the end.
2nd Half Observing Specialist: Camron Hastings
	No problems. Some cirrus at times. The slit camera died part way through
the night. It kept saying "Time Out when Requesting Camera Status" I
rebooted the slit PC and all was fine again.
