Upon reaching the site I found the ITF relocking. After a brief alignment of the PR/SR Mirrors, LOW_NOISE_3_SQZ was reached at the first attempt at 13:50 UTC, ITF back in Science Mode from 15:32 UTC.
At 15:07 UTC I set the ITF in Commissioning Mode to allow the planned ISC activity, DIFFp set point error signal test, carried out by Mantovani. The work could not be concluded due to an unlock at 15:22 UTC due to an earthquake (M 5.6 - 9 km W of Sulusaray, Turkey, 15:11 UTC). After various attempts we were able to reach LOW_NOISE_3_SQZ at 16:53 UTC, and the second planned activity, ENV Acustic Injection, started (see report #64024).
ENV Activity concluded at 18:11 UTC and ITF back in Science Mode. A quick adjusting period, from 18:16 UTC to 18:17 UTC, was done to allow the switch off the Speaker PDU.
The ITF unlocked at 19:34 UTC, relock in progress.
