In-chamber cleaning in HAM-9 got through wipe down today. Second vacuum was delayed by the absence of a clean vacuum brush which was retrieved from a Class B bake late in the day. (One had not been set aside as the crew normally does.) In the meantime, the east door was cleaned so that it is ready to be put back on Monday.

The dome was replaced on BSC-4 this afternoon and then the cleanroom was moved over HAM-10. We will re-sample the HAM-10 floor, pull the dust barrier, wipe down the floor, and then sample the floor one more time. 

A cleanroom was also moved over HAM-11/12 so that first and second cleanings can begin ASAP.
