QUICK SUMMARY:
H1 had a lockloss about 4.5hrs ago, but has been UP about 3hrs.
For the Alarm Handlers there was a "Not Connected Error" window up (and WHITE alarm for dust monitors) at 2:23amlocal which cleared up in 3 seconds.
For those who felt it (or heard) there was a M2.8 earthquake in Richland last night (at 9:18pm Local). H1 rode right through it and it was only seen on our seismometer DMTs for the 3-10 & 10-30Hz bands (it's the orange EX x-axis line at about 11hrs --see attached-- (I happened to look at it last night after my sister texted me about it while she was working at the Emerald; she (and I) didn't feel it.) :)
