Ops Eve Mid Shift Report
Following a lockloss at 00:40 UTC with an unkown cause, H1 has now had two unsuccessful lock attempts, both losing lock during or soon after TRANSITION_FROM_ETMX with ETMY and ITMX saturations. Higher winds may be contributing to the issues; gusts have been up to 30mph. I'll continue to monitor this lock attempt.
Third time was the charm moving past TRANSITION_FROM_ETMX; only one ETMY saturation during that state.
H1 is back to observing as of 04:03 UTC.
