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 flux at geosynchronous orbit has fluctuated near the event threshold value of 10 pfu for most of the day, though now appears to be undergoing an enhancement due to the recent shock passage. As a result of near-threshold activity, a 10 MeV proton event has been in progress since 30/0245 UTC. Max flux observed today is 19 pfu, at 30/2355 UTC.

C. 地磁活動總結

Geomagnetic field activity has been quiet to active. Most of the day was dominated by ongoing effects from yesterday's shock passage, with an extended period of southward IMF producing active conditions during 30/0300-0900 UTC. Active conditions returned late in the day, when an additional shock passage was observed at the ACE satellite at 30/1932 UTC, followed by a sudden impulse of 27 nT observed at Boulder at 30/2010 UTC. This event is presumed to be an early arrival of effects from the powerful X-class event of 28 December.

D. 地熱

STRATWARM ALERT EXISTS STRATWARM SUNDAY WARM AIR COVERS MOST OF THE POLAR REGION IN THE UPPER AND MIDDLE STRATOSPHERE, FURTHER PENETRATING DOWNWARDS. THE TEMPERATURE GRADIENT BETWEEN 60N AND THE POLE WILL BE REVERSED DOWN TO 50 HPA, AND MEAN ZONAL EASTERLY WINDS ARE EXPECTED BETWEEN 10 AND 1 HPA AT 60N. MAJOR WARMING IN PROGRESS.
