First cleaning and vent prep staging are complete. Dust counts in the HAM6 cleanroom are excellent. They have been below 100 all day, even with the high level of activity around and in the cleanroom. There was one very high spike (18k both 0.3 and 0.5u particles), while there was cleaning going on inside the cleanroom. These cleared quickly after the crew left the cleanroom. Posted below are trends of the HAM6 dust monitor for the past 12 and 24 hours.   

   I did a compassion check of the new dust monitors and my HHPC-6 hand-held. No more than 10 count difference between the two monitors over several samplings.
