                               ACTIVITY LOG
The telescope was opened at 19:30.  Charles Hoopes was on site, training
Mark Bransford.  The seeing was very poor.
(no comments)
I was able to observe 2237 for the Lens Monitoring program.
Chris Stubbs was available for the DD01 time.
COMMENTS:Our program was a mixed success.  We did succeed in detecting PNe
with DIS operating as a dispersed imager.  Unfortunately, our main objective
was to compare the throughput with medium and high resolution gratings, and the
instrument was not configured properly(wrong grating set in place). Our main
objective was defeated by this...otherwise, things went OK.
There are several reasons I did not have the correct gratings in place:
I just arrived at 5:30PM, and was helping Charles get set up to take biases.
I did not get to the email that Chris sent about the grating swap until much
later.
There wasn't a note posted to the board stating any swap needed to be done.
I had a slight problem getting the TCC to run properly at the beginning of the
evening because a session was left running in the dome.
Forecast:(4:30am)
.TODAY...MOSTLY FAIR TODAY WITH A FEW AFTERNOON THUNDERSTORMS IN THE
HIGHER PEAKS.
.TONIGHT...MOSTLY FAIR WITH A FEW EARLY EVENING THUNDERSTORMS IN THE
MOUNTAINS.
.MONDAY...PARTLY CLOUDY WITH A SLIGHT CHANCE OF THUNDERSTORMS
MAINLY IN THE MOUNTAINS.
