TITLE: 04/20 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 156Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:

Lockloss Sandwich:  Shift started with a lockloss during the first 30min and a lockloss near the last 30min of the shift.

Also posting  a spectrum of the HAM5 STS seismometer during Richland earthquake---mainly because when Robert walked in the Control Room he was surprised to not see anything on the low-frequency seismic plots on nuc5....but it's mainly because we don't have 1-3Hz up there.  The attached spectrum does show a big bump in that band for sure.  (along with lines at ~7Hz and around 32Hz.)
