STATE of H1: Planned Engineering
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 41mph Gusts, 30mph 3min avg
Primary useism: 0.10 μm/s
Secondary useism: 0.31 μm/s
QUICK SUMMARY:
Got an overall summary on the status of H1 recovery from RyanS.
Whoops! Looks like I was too focused on turning off excitations to post summary last night (left site at 8pmPDT). Summary:
TITLE: 03/11 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:
It's been mentioned earlier, but it sounds like there are issues with beams observed on some in-vac sensors, but not on others. This evening I attempted a test commissioners mentioned as they left in the evening: drive RM1 & RM2 at a low frequency and see if one can see anything on ASC REFL A (& B). Made an attempt at this, but not sure my set up was optimal. Turning OFF the excitations before I leave (RM1 & RM2 were driven from roughly 2-3utc---with tests in the hour or two before that).
Very windy night!
