Attached are plots of dust counts > .5 microns. The dust monitor at location 11 in the LVEA (between the clean room over HAM 12 and the clean room over the ISI/SUS test stand) had stopped for an unknown reason. I went out into the LVEA and it had been moved several feet. It seemed fine after I checked the settings and hit run. The dust monitor at LVEA location 6 (in the H1 PSL diode room) had a sensor alarm and was removed. It looks like it may have occurred around Nov. 13 2011, 21:40 UTC.
