TITLE: 03/09 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Aligning
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY:

Today (and last night) was ETMx-related with (2) ETMx locklosses (one overnight & one at very start of shift).  Then had almost 5hrs of downtime with 3 locklosses in a row at LOWNOISE_ESD_ETMX (resulting in making some Calls for help, but H1 came back on its own...after pausing for about an hr before this troublesome state---see alogs).  Keita also suggests some measurements we should run next time we are locking.  Secondary microseism has mostly been flat (but maybe if you squint at it right, you can see it possibly drifting down).  Winds have  been around 20mph for much of the last 6hrs.

H1 is finally thermalized, so a calibration could be run (but microseism is high still, so I'd be wary...esp with the grief of getting through LOWNOISE ESD ETMx this morning).
LOG:

• 1435 ETMx Glitch LOCKLOSS
  • 1438-1502  Initial Alignment
  • 1541 lockloss @LOWNOISE_ESD_etmX
    • 1548-1554 DRMI bad, so ran CHECK MICH FRINGES + PRMI
  • 1629 lockloss @LOWNOISE_ESD_etmX----> (perhaps look at alog82912)
  • Increased ramptime & timer for LOWNOISE_ESD_ETMX for 3rd attempt thru this state.
  • 1735 lockloss @LOWNOISE_ESD_etmX  (time changes above did not work, so backed them out).  Started Call List protocol.
• 651-1621 SEI_ENV @USEISM (now at CALM)
  • 1721 back to USEISM
  • 2255 back to CALM
• 1924 Back to OBSERVING (w/ nothing new done...other than pause at MAX POWER for about 52min)
• 2003 alert for an EQ from Mexico (I think Seismon meant to say this was a M4.1 from Malibu, CA at 2003utc)---either way this did not affect H1 or show on our seismometers.
