LOG:
16:22 UTC Kyle left. He was working in the vacuum prep lab at the end of the hallway when I arrived.
17:44 UTC Multiple EY saturations. A comb appeared in DARM from 500 Hz to 1 kHz. Lasted ~ 1 minute. Looks similar to what Nutsinee posted in her owl shift summary.
23:10 UTC TCSY chiller flow is low verbal alarm. Trend showed it recovered.
23:44 UTC Single EY saturation. Everything in DARM below ~300 Hz jumped.
00:00 UTC Thought I briefly saw red squares on the CDS overview under end Y, but they disappeared.
