DQ Shift 16 March - 19 March 2017
Very good, quiet 4 days. Overall duty cycle was 91.4%, with range reaching just over 70 Mpc at times
- 2 24+ hour lock stretches
- Some wind issues Thursday morning (UTC) and Saturday evening (UTC)
- Strange trend in low-frequency noise on Sunday: started low, peaked at 0800-1000 UTC, then came back down slowly; possibly periodic with 24-hour period, uncorrelated with microseism
