              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Closed due to weather.  Rain started around 19:00.
I took some TSPEC rotation Darks for Russet. (note, rot.0001 thru 0006 had the dome lights on).
I took 10 darks in 10 deg increments starting at 0 mount going to +180 deg, then back to 0 mount and going to -180 deg.  The rotation angle is also in the FITS comments.
Wind picked up at the end of the night, not that made much of a difference with the humidity and clouds.  I gave up at 04:30.
