STATE of H1: Observing at 160Mpc
INCOMING OPERATOR: Austin
SHIFT SUMMARY:

6:30 UTC stepped outside to secure the Weld Shop Door.

7:14 UTC another super event candidate S231118ab

ITMY MODE 5 has been slowly rising for the last 12 hour.
I just happened to notice it when I saw that the Darm screen showed the Violins had crossed into the 10^-17 line.
I then trended back the Violins and noticed a trend that I couldn't see when only looking at the violins on a 10 minute scale.
I turned H1:SUS-ITMY_L2_DAMP_MODE5_GAIN off for the night.
Next shift operator please check the violins. ITMY Mode 5 is currently at 2.86.

The temperature of the VEA AV Temp has stablized at 65 Deg F. in the last 12 hours.
