With a lock stretch of over 7.5 hrs at ~23.2W & a range of ~57Mpc, here is a picture of last night's lock stretch. Just before 9am, H1 lost lock (no obvious reason, as we continued operating in an Undisturbed state), the Intent Bit was taken to Commissioning, and Ellie started SRCL work.
Here are the trends for the various DC, 18MHz and 90MHz powers. Some small variations are visible in the first hour, which are probably due to thermal loading.
Attached is a plot of the default lockloss file Travis and I ran for this lock. (time entered was 8:53:00am PST).
