NOTES/ISSUES/PROBLEMS From the 9am status meeting: Over the weekend, 8 supports, 9 dumps. 2 command uplinks, good through 273:03:31. 3 more command loads to go for SEP2400c. As reported in SOT_reports/Sept_25_2000_H431.txt, CAP 657C was run and successfully inserted the LETG. LETG will be used the entire rest of the week, and be removed via real-time operation at 276:16:20. OCT0200 initial products out. Being rescheduled in response to email comments. Load review probably tomorrow. Expecting final OCT0900 OR list today. Problem getting data through psicorp during the LETG insertion prevented acorn from running, and stopped the chandra.snapshot. Restarted this morning. J. Nichols has identified two fixes for data interruption, but they have not been implemented.
