We visually inspected the windows on the HAM1-HAM2 septum and wiped the bottom of the cylindrical window recess. I found nothing that might be a structural risk.

IFO REFL window (bottom +Y) had two big particulates as well as tiny ones. Gerardo blew off the big ones using an empty iso-propanohl squirt bottle as an air puffer. After that he wiped the recess for the window and picked up something, which we guess is one of the big particulates that were removed from the window. Tinier particulates stayed. There was also about half to 3/4-inch long line close to the top of the window. It might be surface scratch, didn't move, and might have been there for a long time. Since it's 1/4" or so from the edge of the optic and very far from where the beam will hit I say this is OK.  

Main PSL beam window (top middle) had tiny particulates but no big ones. These were not moving when Jordan tried to blow them off. I say these are fine.

POP/ALS window (top +Y) as well as unused window (bottom -Y)looked fine.
