Ops Day Mid-Shift Summary

   Good observing first half of the shift. Received a good GRB Alert. 

  Dropped out of observing twice, once for a TCS Laser glitch and once of a Squeezer unlock. Both recovered and we were back in observing in less than 2 minutes. 

   IFO is in the hands of the commissioning team as they run the Wednesday calibration measurements, from 20:00 (13:00) to 22:00 (15:00). 

   Wind and microseism are bit elevated. No other problems or concerns.

This was the TCSY laser relocking...again. The last time it relocked was July 2 17:10 UTC.

The CO2Y PZT seems to be moving much more than CO2X.
