QUICK SUMMARY:

HAM1 JAC alignment work continues (I pressume similar for SQZ alignment.)   There is a plan to swap out a ceiling HEPA Fan for the anteroom of the H1 PSL enclosure this morning.  Also prep for HAM3 venting is on the docket when HAM1 work completes (i.e. lock HEPI, chamber cleaning, etc.)....and  also venting the corner as well. 

LVEA is still Operations laser SAFE (or bifurcated for HAM1 + SQZ work and laser goggles required at height).  Warmer this morning April Fool's Day and rainy.
