Ops Eve Shift Summary

TITLE: 07/17 Eve Shift: 2330-0200 UTC (1630-1900 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: After alignment on IOT2L wrapped up, Jennie, Keita, and I made some attempts at locking the IMC, but ultimately were unsuccessful (see alog91086 for details). I've left the IMC and JAC Guardians in 'DOWN', and I unlocked the ISS while the PSL thermalizes a bit more overnight. The LVEA remains Laser HAZARD and pumpdown of the corner and HAM1 volumes continues.
