B. Proton Events
THE GT 100 MEV FLUX BEGAN RISING AT 06/0825Z AND REACHED A MAXIMUM OF 2.9 PFU AT 06/0840Z. FLUXES DECAYED SLOWLY DURING THE DAY AND WERE NEAR BACKGROUND AT THE END OF THE PERIOD. THE GT 10 MEV FLUX BEGAN TO RISE AT THE SAME TIME AND REACHED A MAXIMUM OF 210 PFU AT 06/0945Z AND THEN BEGAN TO SLOWLY DECAY. FLUXES WERE NEAR 10 PFU AT THE END OF THE PERIOD.
C. Geomagnetic Activity Summary
THE GEOMAGNETIC FIELD WAS QUIET TO SLIGHTLY UNSETTLED.
D. Stratwarm
None.
