RADIATION SUMMARY ----------------- Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: The solar flare activity level was moderate. A total of 12 C and 1 M class events was recorded yesterday. (http://www.dxlc.com/solar/) CMEs reported for past two days: August 10-12: No obviously Earth directed CMEs were detected in LASCO images.

There is definitely also a need to replan for late next week. S/C: - GOT/IST: - DATA: SOT: At yesterday's telecon, we decided to eliminate the extra time pad for rad zone entry, since the radation belts have returned to normal. This will be implemented in the AUG23 load. MEETINGS -------- Data ---- On colossus (/dsops/GOT/input), - Aug 13 02:17 2004_225_2059_226_0234_Dump_EM_64015.gz.
