              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
First half was mostly clear with excellent seeing, sometimes too good for transit photometry (but the targets weren't bright enough for the diffuser).  The big weather event started with softer seeing by 1:30, then clouds around 2:30, quickly getting thicker.  We mounted DIS but couldn't see very bright stars so I closed at that point.
The JHU class was onsite and this time I got their names:
Mubdi Rahman
Alexandre de la Vega
Kristin Sotzen
Weichen Wang
Joseph Serigano
Anna Carter
J. Bradley Bowers
Clara Brasseur
Michael Busch
Jon Schroeder
Yi-Kuan Chiang
