(* means a trouble report has been issued or appended to)
First Half Observing Specialist: Camron Hastings
Second Half Observing Specialist: Russet McMillan
The telescope was not opened all night due to rain, hail, snow, fog --
basically most conceivable forms of bad weather.  Some Echelle work
was done during first half, and SPIcam was being pumped.  At 03:35 and
again at 03:55 there were some power flickers less than one second in
duration -- not enough to kick over to generator power, but enough to
trip the shutoff valve on SPIcam's pump.  At 05:30, when the power had
been stable for some time, I opened the valve again.

used is north=0 degrees, east=90 degrees. The dust count is for the
particles > 1 micron per 0.1 cu.ft.
