Yesterday, I was supposed to run some normal & accepted H1 calibration measurements, but unfortunately an EQ changed my plans.
Today I chose to run these measurements. Before running the measurements, I wanted to minimize time out of OBSERVING as much as I could, so I got everything set up ahead of time. I opened up (3) separate DTT sessions with each measurement ready to go (so I can easily run them and also save them while running other ones. When starting a measurement, I turned on my Timer on my phone so I would get a reminder when it was done.
note: Attached is a screenshot of my desktop with all three completed measurements.
- 16:53: STARTED measurements
- 17:26: COMPLETED measurements
- 17:31: Back to OBSERVING (delayed, because I turned ON SEI_DIFF & contemplated staying out while I did VEA holiday site walkthroughs, but an EQ was inbound, so decided to hop back into Observing & monitor EQ.
H1 Status:
- SEI_DIFF is OFF (well, the node is CORNER_DIFF_CPS, but BIT channel is OFF)
- Microseism is fairly high (0.4um/s for 0.1-0.3Hz)

Noticed DIAG MAIN message:
"PCAL: PCAL Y OFS servo malfunction" Will send a text to Jeff K.
After I posted this alog, Jenne phoned because she noticed we didn't have some of our Cal Lines. She said we don't want to be in OBSERVING w/o out Cal Lines, so I took us out and then we investigated PCal Y.
We brought up the PCal-Y medm and the gray time series box eventually showed a flat line at around -8. (this should be "fuzzy" instead....it looked like it was stuck at a value). So we toggled the Loop Enable button (clicked OFF for 3-secs and then turned ON). This brought back a more real (& fuzzy) signal & we were happy.
H1 Had Cal Lines Back!
(Since we were out of Observing, this is when I started the Holiday Walk Through of VEAs.)
