We'll be down for the entire maintenance period (8:00a - 12:00p PDT) tomorrow, as there are activities that require laser safety which are expected to take the entire 4 hours. This means we don't expect to get much observing data during the work day tomorrow, especially if the current perfect storm of wind vs. microseism continues.

Other than the HAM1 HEPI pier grouting, we don't expect any of these tasks scheduled for tomorrow to impact the IFO's lock acquisition abilities or to change its configuration. However, we must be mindful of how the HEPI pier grouting may affect REFL ASC by changing HEPI alignment.

I attach a shot of the whiteboard. Lots of activities, but essentially all of them can be done in parallel. The DAQ restart (to store some SDF diagnostic channels in the frames) is scheduled first, to get it out of the way for those tasks that do need the DAQ (namely PCAL Inv. Actuation Filter characterization after it's installed).
