TITLE: 06/21 Owl Shift 07:00 – 15:00 (00:00-08:00), all times posted in UTC

STATE of H1: Observing

INCOMING OPERATOR: Patrick

SHIFT SUMMARY: 6.2 EQ NE of New Zealand knocked us out of lock around 09:24 (01:51). After initial alignment and a few locklosses, was able to relock and go to Observing. Observing now for 2.5 hours.

LOG:

07:00 (00:00) Start of shift

08:21 (01:21) Switching to EQ mode for 5.3 NE of New Zealand.

08:36 (01:36) Switching back to windy. Experienced a glitch as the nodes arrived (maybe correlated).

08:51 (01:51) Switching to EQ mode for 6.2 from same area as previously.

09:25 (02:25) Lockloss due to EQ, had a much greater effect than the EQ Response estimate indicated

10:39 (03:39) Sufficient ringdown to try locking, but it looks like the beam is clipping on the ALS-Y camera. Starting initial alignment

11:03 (04:03) Finished initial alignment (still see some clipping though). Relocking

11:30 (04:30) Two similar locklosses so far from DRMI_LOCKED_CHECK_ASC (maybe because EQ was still ringing down)

12:36 (05:36) At NLN, accepting sdf changes and entering Observing

15:00 (08:00) End of shift
