Ops EVE shift summary

Quick Summary: Commissioning. PR gain and noise hunting. Carl is working on PI. We stayed locked at 40W for a while. Shortly locked at 50W before Bounce mode and PI broke it.

Log (All time in UTC):

0:04 ETMY ISI (PAYLOAD WD) tripped. ETMY SUS is frozen. Dave restarting SUSEY IOP.

4:33 Sheila to ISCT1 aligning POP diode

4:49 Sheila back

~05:05 Ran A2L

 

- Something interesting happened: As PI started ringing up (ITMY 14979Hz and ITMX 15521 Hz) , moving SRM in the corret direction in order to improve AS90/POP90 helped keep PI under control.
