STATE of H1: Planned Engineering

INCOMING OPERATOR: None

SHIFT SUMMARY: Started the shift by taking down the IFO. The followed the vent plan from step 17-21. Accepted all the safe.snap SDF diffs. Left the ISI SDF diffs alone since it's showing the OBSERVE.snap rather than safe.snap. See attachment for details.
