Spent an average of 70% of each day in observing, consistentlly around a range of ~150-160 Mpc.
Most locklosses seemed connected either to earthquakes or commissioning
Continuing to see periodic bursts of noise around 32 Hz that was noted in last week's DQ shift. It occurs on the order of a few times per day and seems connected to ground motion (potentially also being seen in floor accelerometers). See Beverly's alog for a more detailed explanation
Starting Wednesday, some short duration low-frequency combs would show up on the order of a couple times per hour. On the spectrograms, it appears to be about harmonics of 4 Hz which could the noise that was noted early in O4 from EX's undamped cryobaffle (see alog)
