This Week's Scheduled MODIS Activities Not Completed:
No SD/SDSM activities were run this week. Monday's activities were deleted from the timeline during the system upgrade. A DR was submitted for this anomaly. Wednesday's activities were not scheduled due to the drag make-up burn which occurred that day. Friday's activities were not scheduled because of planning aid issues related to the burn. The nominal SD/SDSM activity schedule should resume next week.
