Steve Nahn requested the SVSEB rack to be power cycled. I did so and notified the sci-co.

<table border=0><td><tr><td bgcolor=#e0e030>The historical file seem to be corrupt again. Different historical files have gaps of data at different times. For example the water ECW file runs from 1040hrs on 11/27/02 to 0052hrs on 11/28/02 then stops. While looking at the LN2 dewar level historical it is intermittent with about 75% of data missing since 1040hrs on 11/27/02. I still have the heartbeat on the historical collect. Bill Noe and Jim Loskot are out of town for the holiday weekend.</td></tr></td></table>

I added some propylene glycol (NFP-50) to CHW ET-2. The level was down to 7.5" from all the air we have bled out of the system. The level is now 11".

I suspect that this is related to a massive Tev quench and the radiation it produced.

Placed HVAC in full and turned on the RFs.  Had difficulty getting BF1 to turn on.  I had to run it up by hand.  It had tripped on overvoltage.

DAQ Ace upstairs informed me that the iFix solenoid display in the control room was frozen. The reboot worked.

Gas readings and mechanical rooms are normal at this time. I also checked the ethylene glycol for the alcohol bubblers. This expired earlier today.
