QUICK SUMMARY:

Quiet morning thus far with only light snow/ice patches observed on drive/walk in.
The DMT seismic FOM appears to be dead again (One of them works and the other is not. I'm trying to remember what the issue was last Tues/yesterday and I believe Dave mentioned to TJ/myself something about a kerberos ticket issue).
ISI Config has been in the Large EQ NO BRSx/y since yesterday morning. Since no one needs H1, will leave in this state (consulted with Jim about it this morning).
L1 had about 7hrs of 90Mpc over night.
