Plans to resume observations were discussed at the end of today's 9 o'clock. Summary of the discussions follows: Plan A (prime): Intercept load NOV0801 has been prepared and will be approved today at 2pm load review. This load starts at 312:0945 with an ACIS stop science followed by a maneuver and then starts observing with obsid 1624, 'NGC5866' at 312:1015. If radiation levels permit, we will uplink and start this load at the 312:0315-0415 pass (tonight 10:15 - 11:15). If the load is uplinked and started then the ACIS team will start a CTI measurement via CAP. The criteria for uplinking/starting the loads will be: GOES Predictors of EPHIN trips P4GM and P41GM 1/3 of RADMON trips. ACE soft proton flux under 5000. Rates are all decreasing. A radiation telecon will be held tonight at 10:15 EST on 305-503-1818, passcode 421 Decision on loads will be made then. Real time EPHIN data out of rad zone will be available during 312:0630-0730 pass. This data will be used to verify that radiation levels are good, (EPHIN channels 1/3 of RADMON trip) or to stop the load if they are bad. Plan B (backup): Build a new intercept load which picks up with obsid 3395, 'MG J0414+0534', at 313:0834. This load will be built today, with target uplink COMM at 312:2000 UT (3pm tomorrow afternoon). This is about 23 hours prior to the next radzone entry. Space Weather Report: Radiation: ACE soft proton flux had decreased to 10,000 at about 311:0000UT but has been increasing since about 0400UT today. Is now (311:1700UT) at about 25,000 with much variability, and still is trending up. GOES: GOES EPHIN predictors were decreasing until about 310:0000UT, then were flat or increasing for a few hours, then have started to decrease again. The levels are a bit below the EPHIN trip levels for P4GM and P41GM. Solar Activity (from Today's Space Weather): There have been several long duration flares in the last two days that could have produced earth-directed coronal mass ejections. Since the onset of the proton storm at approximately 1700 UTC on 04 November, the LASCO instrument has been saturated by the particles and it is nearly impossible to determine if any CME's have been produced or if they are earth-directed.
