QUICK SUMMARY:

Nice shift for H1 with a lock over 12.5hrs.  Also ran the Saturday calibration.  Microseism is still high.

LOG:

• PSL Dust Alarms have been alarming throughout morning.
• 1847 Changed ITMy MODE-5 to Rahul's newest settings after chatting with him: FM6 + FM8 + FM10 Gain +0.01 (+30deg phase)
  • BUT:  This still is not set in Guardian!  Guardian still uses the older settings (60degphase + a gain of 0.0).  If Rahul is happy with the new settings above, we will need to:
    • update lsc_params &
    • Load guardian(s):  would this be VIOLIN_DAMPING only or also ISC_LOOK as well??
• 1930 Calibration Time (but first---wanted to see if taking VIOLIN DAMPING to SIMPLE bumps out of OBSERVING)
  • Taking VIOLIN DAMPING from DAMP_VIOLINS_FULL_POWER to DAMPING_ON_SIMPLE does in fact take H1 OUT of OBSERVING!
  • Restored nominal gain for IY mode1
• 1947 SEI_ENV transitioned to CALM (had been at USEISM since 447utc)
• 2029 PI31 alert, but only for a few seconds.
• 2130-2151 PCal Lab work (tony)
• 2317-2327 Grabbing an optic & checking terminte status in the optics lab (robert)
