Tuesday day shift summary
Please remember to communicate with the control room when you are embarking on work in the VEA's.  There were enough people at BSC3 today to make a Shriner's convention, but ops didn't know who and when.  This makes it difficult to respond to questions that we receive in the CR.  Another nag -- carpool on trips to the outbuildings with site vehicles when possible on days like today when both end stations are in play.

Site support:
** The rug vendor now arrives early on Tuesday mornings (~7:00 AM)
** The office trailer came off the gravel today and is resting on the roadside near the front of the corner station.  It's scheduled for final departure near 9:00 AM tomorrow.
** Lots of noisy activity on the corner station roof today 
** Insulation removal continues on the near section of the Y arm (Y1).  The control room strip chart now reads the Y1 vacuum.
** There appeared to be no Praxair delivery today, but I may have missed it.
** Update of the GC switch occurred.  Network and phone outages appeared to cease at midday.

Interferometer activities:
** Apollo worked on viewports at EX this morning.  Alexa and Sheila removed one side of the first contact on these this afternoon (no work permit on this because the network was down.  John W cleared the work).
** LVEA has been in laser hazard all day.  EX entered laser hazard near 3:30 PM.
** Kyle is delivering instrument air to the controls of GV6, which remains hard closed as of 4:00 PM.  He'll leave it closed tonight.
** EE crew grounded power supplies at EX this morning.
** Rich A made measurements on an ISCT1 PD, and he checked ESD cables at BSC3
** Patrick relocated the dust monitor code
** Dave and Jim installed RCG 2.8, which seems to be working properly
** When the PSL controls went down this morning because of the upgrade, Sheila did a burt restore to re-lock the mode cleaner
** Work continues at HAM2 (possibly the PD array installation which was scheduled for today).

Alarms:
** Lots of CDS alarms due to system work (none were surprising)
** Occasional dust alarms in areas where work was occurring.  There was one episode of 80,000(+) 3um early in the afternoon at BSC3 that was not repeated.
