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

A greater than 10 MeV proton event accompanied the long duration M1 flare and CME that occurred at 25/1514Z. The proton event began at 25/1855Z and remains in progress. The peak so far was 55 pfu at 25/2305Z.

C. 地磁活動總結

The geomagnetic field was at active to severe storm levels. The shock observed at the ACE spacecraft on 24/0600Z was followed by a prolonged period of southward IMF Bz that lasted through midway on 25 July. Bz ranged from -10 to -20 nT for much of this period, while solar wind speed was elevated in the 550 to 700 km/s range. Consequently, severe geomagnetic storm levels were observed at all latitudes. It is likely that this activity was associated with the complex series of CMEs observed on 22 July. Late in this period, a discontinuity in the solar wind suggested that transient flow from the multiple CME activity on 23 July had arrived.
