Attached are plots of dust counts > .3 microns and > .5 microns in particles per cubic foot from approximately 6 PM Nov. 14 to 6 PM Nov. 15. Also attached are plots of the modes to show when they were running/acquiring data.

The sensor may be failing in the dust monitor in the optics lab (H0:PEM-LAB_DST1). The calibrate failure alarm is being raised momentarily (status of 1 in attached plot).

Dust monitor 4 in the LVEA may have been turned off after the cartridge install. It was in the clean room over the test stand farthest from the Y manifold.
