As per our phone conversation, please use the majority of the PU01 time
and, if necessary, a small amount of the UC01 time, to obtain deep I-band
images of the field specified in the attached message.  As you noted, it
is probably possible to start slightly before twilight in I-band, especially
given the moonlight conditions.  A few deep images with small offsets (a few
arc secs) between them would be ideal.  Please make these images available
for anon ftp in some place and notify all the cc recipients of this message
of the location.

If possible, also grab a quick exposure or two (r'-band has priority) of
the primary lens monitoring targetr (2237).  However, we should try to
minimize impact on UC01, so od not do 2237 if this will carry us into UC01
time significantly.

Telescope time for these observations should be accounted to PU01, not DD01.

Many thanks!
