Comments:
A bad NIM-ECL channel for the scalers was causing the 1e_new rate to
fluctuate dramatically. WB & KEG moved the cable to another channel. So,
future people on shift, be aware that this has changed the order of the
scaler rates on the scaler window (make sure you look at the labels!).
Also, the old "VETO" label has been changed to the more descriptive
"H2=SF=3".

At 15:30 power was lost to the CUB (Central Utilities Building). This caused
us to lose our cold water supply. The two main effects of this are:
1) The magnets warmed up very quickly, changing the B field and thus we lost
   the beam
2) The ac in the counting room is not working so as many of the computers
   and electronics were shut down as was practical (in the first 30 minutes
   there was a 2.5 degree C increase in temperature).

Good Afternoon,
Jason & Matteo
