Mid-Shift Status: H1 Struggles To Get Much Further Than ENGAGE ASC With High MicroSeism

H1 continues to struggle with high microseism.  Alignment, for the most part, continues to look decent with flashes looking fine for DRMI (and PRMI when ISC LOCK took H1 there).  But have only made it as far as MOVE SPOTS in the last 2.5hrs (Engage ASC takes a while and this is where we have lost lock quite a few times.).  And for various states, one can clearly see lo frequency oscillations (~7-9 second period....see attached at ENGAGE_ASC_FOR_FULL_IFO).
