(* means a trouble report has been issued or appended to)
1st half observing specialist: Karen Gloria
2nd half observing specialist: Tia Hoyes
The telescope was opened at 19:05, under a mostly clear sky.  I had to
close at 20:15 MDT, shortly after twilight flats were finished.  A
dense rainshaft appeared over Alamogordo.  I decided to close until
that dissipated.  I was able to reopen at 21:45 MDT but the humidity
remained a little high.
COMMENTS:Jerry Kriss, Zlatko Tsvetanov, and Randy Telfer
After a short delay due to nearby showers, Karen opened the dome and we
started observing.  Seeing wasn't so great, only about 1.5" FWHM.
Got decent r, i, and z images of four fields surrounding z~2 BAL QSOs.
Signed off Spicam at ~0115.
I had to close at 01:15 due to heavy clouds and impending rain.  It began
raining at 01:45, and stayed humid all through the rest of the evening.  The
skies started clearing around 05:30, but the humidity was still jumping
around.
