This is yesterday's (Feb. 25th) report.

[mTakahashi, Yamada]

We completed to install the MN/PF OpLev base at IXC.

*MN OpLev*
We mounted all MN OpLev bases.
Installation procedure was the same as klog16077.
"+X -Y" (photo1) and "-X -Y" (photo2) were installed in this work.

*PF OpLev*

We mounted all two PF OpLev bases (photo3).
We first mounted the ICF152 optical viewport on the cryostat.
Then, the OpLev base was clamped to the neck of viewport.
The optical table was leveled with bubble level.
We found there are cables infront of viewport inside the cryostat, we should remember moving it later (photo4).
