Work permits were signed and filed after morning meeting. The cleanroom from BSC3 was moved to BSC2, the East Bay cleanroom was moved over HAM4 and then both chambers were cleaned. The viewports and feedthroughs were removed from HAM4 north door and the north door was removed from the chamber. 

The plan is enter at HAM4 ASAP tomorrow and get the sampling done on the BSC1 Elliptical Baffle and then de-install it. Then we'll install dust barriers and remove BSC2's dome so that the SEI stack can be removed before lunch tomorrow.
