Instrument: MODS

Summary:
Scattered clouds at opening that cleared up a few hours later.  0.7-1.5"
seeing.  Started with MODS and observed ND_grb.  Attempted to observe
qso1145m3, but the secondary mirror ripped multiple times, in spite of 
high elevation, so we gave up on MODS and switched to LBC.  Observed N4258, 
UVa_SUPER/GON_UNB_[1-2]_UVA, N5194, and M101.
