This appears to have been caused by electron contamination of the P4GM channel. This was ~20min before the scheduled RADMON disable. It was desirable to pickup science observations with obs IDs 5169 & 5170, which are coordinated with XMM-Newton. Since they are near 90 degree pitch we needed to be at a cold at attitude for some time before beginning these these observations. Therefore, the Replan load was to be configured for uplink during the 2004:182:05:45 to 06:45 pass, with a move to a cold attitude to allow sufficient time for cooling prior to beginning of obsid 5169 at 182:1257. A FOT-MP review of the thermal situation for EPHIN under this assumption found that no re-arrangement of existing targets could maintain good EPHIN temperatures during the next orbit. This is due to losing the time at a cooler attitude when SCS-107 interrupted the load. It was decided to produce a short term replan (JUN3004B) which would include the two co-ordinated observations, then move to ObsID 4548 to get to a better attitude from a thermal standpoint. A follow-up replan load will be produced today, covering the remainder of the week. SOT-MP will provide additional targets at cold attitudes for this replan. Currently running replan load JUN3004B on ascending leg. Observations of 3C273 will begin at 182:1257. Solar proton levels are decreasing from the small bump-up of yesterday. Currently under 50. 3-day Solar-Geophysical Forecast issued Jun 29 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to continue at very low levels. There is a small chance for a C-class flare from Region 639. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet to unsettled with occasional active periods. The current weak disturbance is expected to subside by 1 July.

We wanted to run the co-ordinated observations and had no time to replan the rest of the week, so we decided to do a short replan for those obs, plus one more, then re-do the week today. - SOT MP has supplied some targets at cooler attiudes, and the replan with these targets is under way. Products out later today for load review - Must uplink in DSS-16 pass at 183:0250-0450 - Will announce when products are available and the load review time. S/C Engineering(Dan): - All OK on S/C, SCS 107 ran nominally, momentum looks good. SOT(Bill): - See above notes on radiation.
