Travis installed the Pcal ETM target on the suspension frame.

EndX was transitioned to Laser Hazard for the Pcal 1047 nm laser.

Checking Pcal periscope structure alignment began by sliding under the Arm Cavity Baffle.  Had do move the particulate witness plate about a foot East from directly under the center of the ACB.

Got a good start on the alignment checks.  Plan to return Monday morning to continue with this work.

EndX transitioned to Laser Safe before leaving.
