Comb appeared in DARM
05:50 a 2Hz comb appeared in DARM from ~20Hz to ~100Hz (as far as I can tell as it gets lost in the bucket)) which resulted in a drop in range to ~63Mpc. I placed a call to Jenne who was on call to inquire as to how I should proceed and the advice was as long as were locked, stay locked. So, we're still locked and Observing at 63Mpc.

I found something in EY SUS rack magnetometer. I've attached the spectrogram of what it looks before and after the comb appeared.
