(* means a trouble report has been issued or appended to)
The telescope was opened at 01:15.  We could not open for the Lens Monitoring
program, due to heavy clouds, lightning, and impending hail.
Mike Strauss, Zeljko Ivezic, and Chris Stubbs all participated in the PU02
run.  They began at 1:15 when the sky finally cleared.  They began by taking
standards and then moved to a drift-scan field.  The seeing started at 1.2
arcsecs, but declined as the sky became hazy.
