               -------------- Activity Log --------------
1st Half Observing Specialist: K.A.Gloria
    The telescope was opened at 19:00 MDT.  Patrick Crotty observed
for Adler.  He managed to squeeze in an echelle spectrum between
sunset and closing time for Adler.
    Tim Heckman and Crystal Martin (JHU) were on site to observe with
the echelle.  Everything went pretty smoothly, aside from a few quirks
in the user interface for the echelle.  They got in some long
integrations on a couple of their science targets.
2nd Half Observing Specialist: N.C.Hastings
    The switchover was uneventful. The first pointing of SPIcam did
show a problem though, we were lost. It turned out that altitude axis
was lost, after this was figured out I corrected it and we did get a
standard field and one SN for UW02, but a loss of 0.5 is a huge chunk
of time when you consider that in a 1.0 hour program you still have to
focus and reset the guider stuff and the telescope as well. We
actually received about 0.2 hours of science observing time due to the
loss of the axis problem and focusing time. Ted Wyder donated a few
minutes to let us finish at least the one target we were on. Ted took
over and all was smooth from there on out...
