TITLE: 06/06 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Jim
SHIFT SUMMARY:
Maintenance Day went until about 22:00UTC (3pmPDT) with biggest activity was the PSL going down for HPO Diode swap out. See other activities below.
After Maintenance, ran an INITIAL ALIGNMENT and had no issues. Started locking and made it to DRMI with no issues (aligned PRMI first). Handed off to Jim & Sheila for evening commissioning.

Notes:
- ISS Ref Signal SDF Diffs: ACCEPT! on SDF (according to Peter)
- Some Cold Cathode Pressure Gauges (i.e. B-channel pressure signals) are in an alarm (i.e. RED) state since they were all powered off during Patrick's work today (& channels are either 0 or unbelievably low [i.e. 10^-11]). OK to IGNORE. They will come back on their own...or could be assisted back.
