TITLE: 07/23 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:
IFO is in DOWN for PLANED ENGINEERING
Not much to update after Ryan S's shift other than:
alog 91199 - JAC Guardian work
alog 91197 - new ZM2 Alignment
Additionally, Gerardo realized that MSR temperatures are spiking seemingly randomly. See attached. RACK2 is showing sharper peaks than RACK1, which implies that the heat source is near there? Tagging CDS in case it's an electronics issue.
