This morning I started floating the BS ISI, after asking SUSsers to lock their optic up. No real problems, beyond a missing wrench that had to be retrieved from staging and a CDS laptop that had too aggressive power saving settings (it would sleep the monitor after 1 minute, enough time to change out gloves...sigh). The ISI is currently floating within spec, cps were regapped where necessary, lockers were adjusted, the actuators were visually inspected for spacing, and cables were surveyed for rubbing. This should mean BSC2 is in a good position for in-chamber testing, but the BS is still locked.
