本報告中提到的任何太陽耀斑都有太空天氣預報中心(SWPC) 應用的比例因子。由於 SWPC 比例因子，據報導太陽耀斑比科學質量數據小 42%。比例因子已從我們存檔的太陽耀斑資料中刪除，以反映真實的物理單位。

B. 質子事件

THE GREATER THAN 10 MEV FLUX BEGAN THE PERIOD NEAR 20 PFU AND DECAYED TO NEAR 10 PFU AT THE END OF THE PERIOD. A SLIGHT INCREASE IN FLUX WAS OBSERVED AROUND 19/1500Z WHICH MAY HAVE BEEN RELATED TO THE M6 FLARE MENTIONED ABOVE.

C. 地磁活動總結

THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED FOR MOST OF THE PERIOD. A SHOCK WAS OBSERVED AT ACE AT 19/1450Z AND A SUDDEN IMPULSE WAS OBSERVED AT THE EARTH AT 19/1526Z. UNSETTLED TO ACTIVE CONDITIONS FOLLOWED THE SHOCK PASSAGE. SOLAR WIND VELOCITY JUMPED FROM APPROXIMATELY 450 KM/S TO OVER 600 KM/S. THE LIKELY SOURCE OF THIS DISTURBANCE WAS A MASS EJECTION ON 17 JULY THAT APPEARED TO BE DIRECTED OFF THE EAST LIMB OF THE SUN.
