(* means a trouble report has been issued or appended to)
The telescope was not opened.  Heavy clouds and sprinkles prevented us from
opening.  John Davis, Jeff Morgan and I spent the majority of the night
working on the new GUIDER installation.  Early in the evening we encountered
some problems with the guider cables that were solved by reseating the
Digital Control Cable Connector on the camera head.  The coolant plumbing was
installed and the focus mechanism was modified to allow installation of the
new Guider Camera. (At this point, it should be mentioned that it is not
possible to REMAP the GUIDER at this time, due to the focus/piston has had
its orientation swapped.)  To Remap just the filter wheel, one must run a
Host session from the TCC, TCC_GMECH, and use the command: 0 (FILTER).
The Rotator was roughly balanced and the hardware for the Guider is completely
installed and functional.  Basic communications between the TCC and the Guider
Mac were tested, but we were unable to test guiding function due to the
weather.  Jeff has stated that mandatory new instrument block be set up before
Guider will be available for general use.
Alan Diercks was available for the GRB run, but the clouds persisted and then
gave way to a heavy and continuous dusting of pollen. (It resembled snow)
