We expect to have an email review Monday and a sit-down review Tuesday. S/C: Yesterday's run of last week's OTG commands on ASVT with the tracker showed no failures. We need to continue this evaluation to track down the problem. A previous run resulted in an overrun error in the Vehicle Dynamics Simulator, so that could be the source of the problem. GOT: Larry Felton and Lockheed are working on the OFLS/ONLS incompatilbility problem. There is a return code with unexpected content. SOT: We ran CAP 729A this AM to insert the LETG. Radiation is quite high, ~1/10 of ACE 2 hr threshold. There was a C6.5 flare yesterday with a full halo CME, and a M6.3 flare today at 1013 GMT with a partial halo CME. Both of these could contribute increased proton flux in the next few days.
