Transition to DAY Shift Update
TITLE: 12/30 DAY Shift: 16:00-00:00UTC (08:00-04:00PDT), all times posted in UTC
STATE of H1: NLN at a solid 80Mpc
Outgoing Operator: Ed
Quick Summary:
I talked to Ed while driving in to get the low-down of his shift. Sounds like he had some issues with various things (i.e. ALS alignment, no Dark Michelson [known], OMC troubles @ DC READOUT, etc.)---making me scared of a lockloss! At any rate, smooth sailing now with LVEA useism at 0.38um/s & minimal winds.
RED Timing error for H1OAF on CDS Overview. I can not remember if hitting "DIAG RESET" will drop us out of Observing, so I will hold off on hitting that button (but will send an email to Dave/Jim).
The h1oaf model's cpu max is 63uS which is right at the alarm level. It would be best to keep checking it does not go above 63 while in observing mode and perform at DIAG_RESET next time we are out of observing.
Will hold off on hitting the DIAG RESET button for h1oaf (since we're not 100% hitting DIAG RESET buttons drop us out of Observing. Do not think it's been tested and haven't seen anything in the alog). Dave says we should keep an eye on this though. He would be worried if it was in the high 60s. Looking at last 60days, this is the highest it has gotten though (see attached plot).
NOTE: Would be nice to test whether we can hit this button and STAY in Observing at some point.
