Jeff B. warned me that we would likely be getting a lot of dust monitor alarms after the PEM system was reset this afternoon. He advised that we can set arbitrary alarm values in the meantime and he will remedy them in the morning. I have been setting the thresholds to 1000 minor and 10000 major as the alarms occur.
Not sure why the PSL dust alarm has been going off tonight. Nothing looks out of normal on the camera views to inside the enclosure. Lots of signal on longer trends of the dust monitors - to be filed as "look into further"...
