- Jodi, Jim, Patrick, Zack, Rodney, Cheryl BSC7 large optics removed - H2 ITMX and FMX. The black glass beam dumps and supports were also removed. Tomorrow: remove weights and one steering mirror, and equipment for removing LOS (lazy susan, lift table). Also: Evaluated the plan for removing BSC4 (H2 Beam Splitter) structures, and decided that going through HAM9 or HAM10, depending on whichever is available first, would be the safest route to go.
