              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Adler observers:  M.Hammergren, M.Brucker, K.Nault
OU01 observers: John Wisinewski, Steven Silverberg, Evan Rich, Mike Malatesta, Kyra Dame, Tarryn Kahre, Matt Scheffler, Brandon Curd, Marcus Keil, Jodi Berdis, Xiaoxian Duan.  Students got a tour this evening.
Beginning of the night we had some thin clouds which didn't cause many problems.  The clouds got very thick in the second half.  We had no luck with Agile, so switched to Echelle.  Even that had trouble, and we fought the clouds the rest of the night.  We stayed open, continually trying to get data that was only partially successful.  We did manage to get a few good spectra in the cloud holes, so it wasn't a total wash.  We gave up when twilight started.
No problems with the secondary tonight.
