(http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was low. A total of 4 C class events was recorded yesterday.(http://www.dxlc.com/solar/) CMEs reported for past two days: July 14-16: No potentially geoeffective CMEs observed.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 2.28E+05 1/1578 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.81E-01 1/525 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 7.65E-03 1/102 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 4.30E+04 1/23256 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

The B products will be out later today. S/C: Yesterday, we tested the patches and procedures for the gyro swap. We had a problem with the final one, the contingency patch for avoiding use of the B side IRU in case needed. The west coast team is rebuilding that patch. We will do a detailed command by command patch today. Yesterday's CAP review resulted in some rework. There is another CAP review today at 10 AM. We'll have a dry run tomorrow at 10 AM. GOT/IST: - DATA: SOT: After the 9 am meeting we had a CAP review for the upcoming IRU swap. We reviewed these CAPs: 883, Top level IRU swap. Approved subject to uplinking new star catalogs with 300" search boxes, and Kevin reworking the load so no commands are issued before 22:30 UTC. 831E, Momentum unload contingency. Approved 830E, Momentum Unload. Approved 861 Reactio Wheel Contingency for IRU Swap. Approved subject to investigating how we can get backup DSN coverage if we lose comm, and how quickly we can switch over. 874, Realtime Product Changeout.
