Ops Shift Transition: 08/19/2019, Evening Shift 23:00 – 07:00 (16:00 -00:00) - UTC (PT)
State of H1: Unlocked
Intent Bit: Locking
Weather: Skies are sunny and clear; the current temperatures are in the high 80s to low 90s. Winds are Calm to a Moderate Breeze. There is no rain on the forecast.
Primary 0.03 – 0.1Hz: 0.02um/s
Secondary 0.1 – 0.3Hz: 0.08um/s
Outgoing Operator: TJ
Quick Summary: The IFO is unlocked. TJ started running Initial Alignment. Working with Sheila on difficulty with MITCH BRIGHT phase. Will continue with relocking when the alignment is finished.
Sheila and JeffB found that the MICH_Bright state of ALIGN_IFO is having trouble (and maybe TJ had found that to be true also in the last couple of days?). Since tomorrow is maintenance and we can work on MICH bright alignment then, we're electing to bypass this step for now. Sheila already did a hand alignment of the BS in MICH_DARK. Operators: If you need to do an initial alignment, instead of letting the INIT_ALIGN guardian go to MICH_BRIGHT, hand-select MICH_DARK_LOCKED and align the BS to make the image on the camera dark and symmetric. This should correspond to a minimum in H1:ASC-AS_A_DC_NSUM_OUT16.
