Radiation levels extremely high. Running first command load of OCT3003C, which executed aneeded maneuver. Remainder on hold pending radiation levels. Radiation discussion summary: "Plan A" is to uplink the remaining segments of OCT3003B not later that the 2003:304:0345 UT comm pass. First observation would start at 304/0626. Chance of doing this are very low. "Plan B" (revised) is to upload at the 305/1215 comm pass (Saturday morning) with first observation starting before perigee passage at 306:1310. "Plan C" is a revised NOV03 load, starting later than Plan B. MP will prepare "Plan B" for review, and also send out current NOV03 products for E-mail review. Radiation telecon at 5pm today to assess situation and update planning info. 3-day Solar-Geophysical Forecast issued Oct 29 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to continue at high levels. The very large and complex Region 486 will likely produce more major flare activity during its remaining 5-6 days on the visible disk. A major event is also possible from Region 488. Geophysical Activity Forecast: The geomagnetic field is expected to continue at severe storm levels through day one. The IMF Bz is now sustained southward at near -30 nT, resulting in severe storm levels. This condition is expected to persist through at least the first half of day one. A gradual decline to unsettled to minor storm levels is expected by day two. The potential geomagnetic impact from today's X10 flare will be assessed next period; predictions for days two and three will likely change considerably. The greater than 10 MeV proton event, currently in progress is expected to continue through day three. The greater than 100 MeV proton event will likely continue as high energy protons quickly stream in from the X10 flare that occurred late in the period.

Did maneuver but has no science in first segment. (Just doing COMMs) - CAPS RUN: 893 303/0402 Disable SCS29 - Dumps current Mission Planning (Ken): - OCT3003C load signed off and uploaded (first segment only) First LS contained a pair of maneuvers to move to a more favorable momentum attitude. - Working recovery "Plan B" and as well as NOV03 see radiation discussions above. S/C Engineering(Dan): - Issue of only acquiring six stars seen yesterday. This is the way the the offline software works, only requires six. Can easily cahnge this. - Another issue seen in high radiation yesterday was that the OBC was dropping stars from the Kalman update. This was due to the distorted centroids due to radiation. - Ran CAP 893 to disable SCS 29 SOT(Bill): - See above notes on radiation.
