At mid shift all is good. Robert will be doing PEM injections until 13:00PT. Air quality from the wildfire smoke continues to be an issue. For 0.3um particle size, the outside air is a little better having dropped from 10 million particles per CF, to 8.9 million particles per CF. In the control room counts are: 0.3um = 11,000, 0.5um = 5500, 1.0um 2300 all per CF. Counts particle for all sizes in the LVEA and both VEA remain under 1000.
