Transition to OWL Shift Update
TITLE: 9/22 OWL Shift: 7:00-15:00UTC (00:00-8:00PDT), all times posted in UTC
STATE OF H1: Jim handed over a nice boring shift (just how I like it!). Earth is not rumbling & winds are calm (below 10mph). He mentioned issues with RF45 they had at the beginning of the current lock (it sounds like if this occurs again, we ride it out? Stay in Observing Mode?)
OUTGOING OPERATOR: Jim W.
SUPPORT: Solo. (Sheila is on-call, if needed)
QUICK SUMMARY: H1 sailing along at 75Mpc.
Guardian has a YELLOW notification about HAM5 related to Master Switch.
A quick scan of DARM (compared to 9/10/15 reference):
- 27.4Hz peak not seen
- 645Hz peak not seen
- A few bumps around 315 & 343Hz observed.
Terramon Update: Reports R-waves (2.4um/s) from 6.1 Chile quake are due here in 16min (8:00utc)! I see the 0.03-0.1Hz already starting a climb (just peaking a little over an order of magnitude (i.e. up to 0.1um/s)...but we'll monitor to see how the ground shakes. Let's see how we ride through it.
