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 proton event that began on 25/1855Z is still in progress. A rapid, short-lived increase in the greater than 10 MeV protons to 2,090 pfu occurred with the shock passage at 25/2250Z. Protons quickly declined and were straddling the 10 pfu alert threshold by the end of the period.

C. 地磁活動總結

The geomagnetic field ranged from active to severe storming. A strong sudden impulse (SI) of 95 nT was observed on the Boulder magnetometer at 26/2228Z. This SI followed the very fast (~31 hours) transit of the full halo CME associated with the long duration M1 flare on 25/1514Z. Solar wind speed increased from the already elevated levels near 600 km/s to over 1050 km/s. After approximately four hours of fluctuating between -15 and +15 nT, the IMF Bz rotated strong southward and ranged from -15 to -25 nT for about 15 hours. The fast solar wind speed and southward Bz combined to produce severe geomagnetic storm levels at all latitudes from 27/0000Z to 27/1500Z. Solar wind speed was still near 900 km/s by the end of the period but Bz was near zero. The disturbance declined to minor storm levels to end the period.
