Informal DQ shift: 4 - 10 March UTC
LHO has not officially joined ER14 so there was no plan to reach "Observing" during this shift. However, low noise was reached for several long locks throughout the week although not at all on Monday and only briefly on Saturday.
The glitching on Wednesday was very bad.
The h(t) spectrum on Thursday looked especially bad.
On Thursday through Sunday, hVeto's round 1 winner was H1:LSC-POP_A_RF45_Q_ERR_DQ. This channel seemed to pick out the abundant glitching at around 12 Hz.
The fundamental and second harmonic violin modes were rung up during most of the shift.
