(* means a trouble report has been issued or appended to)
1st half observing specialist: Loomis
The telescope was opened at 16:45 MST.  DIMM was reporting
sub-arcsecond seeing during twilight, so after Armin finished his
twilight flats I took some of the UW07 time to take a set of .1 second
SPIcam exposures for Jeff Morgan.  After that was done, Armin observed
for UW07.
Since the seeing was sub-arcsecond, Xiaohui Fan asked Matt Holman if
he would swap some time at the beginning of PU04 in exchange for an
equal amount of time at the beginning of PU07 in order to image an
object that was setting.  After that, Matt Holman observed for PU04.
We saw a few trailed images.  I'm not sure of the direction of
trailing, but they were trailed about 2-3 arcsec.
I edited the focus offset in default.dat this afternoon, so instrument
foci are now near zero.
2nd half observing specialist: Deglman
Xiaohui Fan and Rita Kim performed PU07 with DIS.  Cirrus for most of the
second half.
