The pumpdown has started at 8:38am

Manasa was here to confirm good alignment of the IFO

Inner jam nuts of AC bellow were torqued to 45 ft/lbs and door nuts were check on opened chambers.

Annulos were roughed down to 500 mTorr

Oplev servos turned off, PSL and green shutters closed before pumpdown started
