Continue cleaning up PEM cabling. This morning we powered off the PEM AA chassis and disconnected all floor bnc cabling for PEM Tilt, Seis, Mic, Magnetometer, and infrasound mic. The cables were pulled back and routed into cable tray over the beam tube. All excess cabling was cut off (up to 20 ft on some cables) and re-terminated. Few cables left to terminate, ran out of time before noon deadline. Plan to run MIC and Op Lever power cables tomorrow.
