SHIFT SUMMARY:

LOG:

ALL TIMES IN UTC

00:18 Tour into control room with Keita

00:28 a2l passive meassurement shows poor coherence in YAW. DARM also shows noise above reference betrween 12Hz and 25Hz. 

02:53 Happened to notice a glitch in DARM between 40 and 100 Hz

05:00 ISC_LOCK guardian node went RED. Restarted the Node.

05:15 Been damping PI modes 27 and 28. Mode 28 PLL wasn't holding steady enough so I adjusted the set frequency from 255.00 to 255.6. This allowed me to have better control. This of course took the Intention bit down so I accepted the change in SDF and resumed Observing.

05:41 FINALLY turned mode 26 with -100 phase and 50K gain. Increased to -60 and 100K.
