Ash Shutdown/Startup / June 15, 2021 / P Gabor ✔✘
Control room =) Use the plot http://abell.as.arizona.edu/~hill/qplot/plots/pms.20210615jhill.jpg (with the date of the second half of the night; authentication on a PostIt note) with caution: It is 10-20 minutes behind.
Control room =) Call the LBT operator 520-626-1466. The operator goes by an alarm triggered by the 25um count (LASAIR particle monitor) exceeding 10 counts per cubic foot. The operator does not receive this information from the plot but rather the particle monitor triggers an alarm.
Control room =) Monitor LBT's Enclosure status (http://info.lbto.org)
Control room =) Go out and shine a flashlight to see the ash swirling in the air for verification.
