This was a showstopper. CSC traced it to a triple conflict in time of occurrence: radmon enable, end of CTI, beginning of next observation. The workaround was to delay rad entry time by one second. A permanent fix will be requested. Discussion was held with SOT MP about techniques for improving the backstop software to catch the SIM command error that occurred a few days ago. OFLS 9.1 testing found a problem - minimum duration parameters in ORs not being processed properly. Although this will prevent further testing of many features, MP will see what else can be tested in parallel, while CSC is being contacted to discuss this problem. Load review today at 2:00. S/C: A CAP will be scheduled to back out the patch and turn off SSR B before the eclipse. GOT: Backup server for GRETA appears to be working. It has been in use for several days. SOT: Radiation is very low.
