At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun):
 * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables.
 * We hung the RM and set its pitch.
 * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system.
 * We installed the bottom section of the security structure to protect the RM/BS.
 * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses.
 * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame.
 * We brought in the new BF.
 * We installed the BF-IRM rods and IRM top plate.
 * We reinstalled the IM flags and other items that had been taken off to use the winch system.
 * We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.)
 * We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT).

 * Remove LBB blade units from PI, then remove blades and send for remachining.
 * Remove LBB rings from chamber and send for recleaning.
 * Unlock BF, adjust ballast masses on IM/RM/BS to correct pitch/roll/vertical.
 * Test, calibrate BF LVDT.

 * SR Stuff		  * We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box.
 * Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.)
 * Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.)
 * Enzo found nearly all in-vacuum cables.
 * Enzo and Shoda-san got several more loops closed on the BS.
 * Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4).
 * Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them.
 * Hirata-san worked on SR procurement.
 * Hirata-san worked with Mirapro to get the SRM LBB installed in the tank.
