H1 & L1 Down Due to M7.6 EQ (+also some high-ish winds)

Another big EQ rolling through.  This one is down near Antartica!  Debated when to transition to "ASC Hi Gn", since R-wave was going to be 45-60min.  But S&P waves triggered EQ Mode + saw a yellow Picket Fence---Clicked on ASC Hi Gn button, but during the transition H1 lost lock.  This might have been too big for ASC Hi Gn regardless, but kinda wished I clicked it earlier.

Winds were peaking just under 40mph around the lockloss as well.

Will be hanging out here for a few hours. 

Now we wait for R-wave which is probably due to arrive around 2135-ish utc.

We lost lock ~3 seconds after CHARD_Y filters bits are changed, there's also a big jump in ground motion at the same time, and it was gusting >30mph at the corner station.
