  Comments:

At 17:15 MCR called to say He2 from Tevatron became contaminated
(probably due to some work done earlier in the day). The pump that gets
the helium from the Tevatron to the VLPCs tripped a while later due to
these impurities.  The VLPC temperature increased and at 18:20 the fibers
were turned off.  The problem was fixed and the VLPCs were cooled down and
the fibers were turned on again at 20:00...

There were a number of hangs unaccompanied by DAQ messages.  These were
traced back to DYCs 3 and 5, which were found to have there "Data In"
lights on.

The nozzle was unclogged twice.

Other than that, pretty smooth....

Good Night,
