At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun):
 * We installed the cut-down ballast mass under the IM and tweaked the IM height and balance.
 * We checked the range of the BF FR.
 * We adjusted the BF yoke by 2.5 mm to make it give ≈0 output for nominal height.
 * We found a good gain setting for the LVDT driver and calibrated the BF LVDT.
 * We set up the optical sensors facing the RM.
 * We assembled the IRM (with OSEMs) around the IM and got it mostly adjusted.
 * We changed the k1visbs model to restore the as-designed mapping of OSEMs to DAQ channels.
 * We confirmed that the BF LVDT actuation coil and the TM OSEM coils were working.
 * We connected up the IRM OSEMs (with the new Type 5-1.7 cables) but found there was an electrical issue: all the OSEMs are reading back the same constant value, around 1115.
 * We left the suspension in a state suitable for TFs from BF GAS actuation to sensing (in vertical) and from RM OSEM actuation to the optical sensors (in horizontal) over the weekend.
At Mitaka (Hirata-san):
 * He got quotes for the SR assembly frame and did cost-reduction negotiations with Aso-san and Mirapro.
got quotes for assembly frame.
 * He did 2D drawings and a parts list for the divided LBB dampers.
 * He contacted a company about SDC.
 * He made a 3D model and drawings for the SR wire clamps.

Kamioka: Mark (except Tue), Ohishi-san, Fabian (except Tue), Enzo (except Tue), Hirata-san, Yoshioka-kun (Fri), Kozu-kun (Thu, Fri).
 * Fix/adjust IRM OSEMs.
 * Add BF cap; cable and test BF-1 and BF-2 picos.

 * 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.
