| TO Comments | Ran successful dmittc tracks at 45, 67, and 179. Reported problem occurred while attempting dmittc at az 315. We were open for two hours in borderline high 0.3um dust, and then for 20 minutes in extremely high 0.3um dust (4 million ppcf in 80% humidity) judged necessary for high priority work. Apologies to the mirror team. Matt, George, Vicki, and Kathryn all helped in fixing MARS to the point where stacking was doable. Stacked all segments except for 9 and 14. Those two are missing. Did not measure stack because of high dust. |
