Posted are the particle count data from the door removal during the HAM6 vent. No serious contamination issues were encountered during the door removal. It appears the north side of the HAM6 area is dustier than the south side. This could be caused by a variety of factors (such as the ITO table on the north side makes it more difficult for the cleaning crew to access this area.)

   Trend data from the permanent dust monitor at HAM6 over the past 48 hours shows no reasons for concern. 

   In general, the area in and around HAM6, as far as contamination control, is in good shape. Kudos to Christina and Karen for all their hard work and dedication to keeping LIGO's contamination sensitive areas very clean.
