This is a summary of the state of the HAM4 and HAM 5 chambers:

HAM5

• The ISI is half locked. The lockers on the south side are locked, but on the north side free.
• SR3 all stages are locked...however the optic is locked in such a way that it sends the HeNe from the SR3 optic onto the centre (ish) of the SR2 optic (still needs investigation into whats going on with SR3 pitch)
• SRM is unlocked.
• Nothing moved on HAM5 table by me/us

HAM4

• ISI is locked
• SR2 is unlocked
• HWS optic positions on table were moved so a rebalance of ISI necessary
• I noticed (the hard way), that it appears that at least 3 of the top mass weights on the 2 stack high SEI masses on the ISI are not bolted to the bottom weight and so can thus move. From memory one is by the north door, one in centre (ish) of the table and one on west side of table
• Note: I believe because of the low purge air a bug flew into the chamber and onto the table. Luckily I was able to get him and wipe in that area, but we need to be vigilant and make sure soft door covers are up when not actively working in the chamber
