Shift Summary - Owl
TITLE: 12/15 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 115Mpc
INCOMING OPERATOR: Jeff
SHIFT SUMMARY: Locked for 7h30
LOG:
- (Following on from 06:37 Lockloss in Niko's alog 53903 )
- 08:29 NLN and Observing.
- This is great! No manual intervention, no inital alignment done and we still have our EQ seismic 0.03-0.1Hz band up above 0.1μm/s!
- 08:55 SEI: Noticed the ETMY LED on the CDS overview (CDS> Overview> Hardware WD) keeps flashing red, though looking at the month trends it seems that this is normal for ETMY?
- 08:59 SEI_CONF changed back to WINDY as ground motion reduced
We have forgotten to reload the guardian violin node as per Cheryl's alog 53891. So this should be done on the next lockloss.
For now I have manually adjusted the violin gains to these values.
Hardware watchdogs (HWWD) flashing red (momentary LED current monitor alerts) is normal. If they are constantly red for several minutes then an investigation is needed. After 40 contiguous minutes in this alarm state, and if the software watchdogs had not kicked in, then the ISI coil driver chassis would be powered off by the HWWD.
