太陽活動報表
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。

SDF 編號 117 在 27 Apr 2007 上以 2200Z 發行IA. 太陽活動區域和 26-2100Z到 27-2100Z的活動分析 Solar activity was very low during the past 24 hours.
Region 953 (S10E49) produced several B-class events during the past
24 hours. As the region has rotated more fully into view, it now
appears that the group consists mostly of a large penumbral area
which contains opposite magnetic polarities, making the group a
beta-delta magnetic classification.
IB. 太陽活動預報
Solar activity is expected to be very
low to low for the next three days (28-30 April), with a slight
chance for an isolated M-class event from Region 953.
IIA. 地球物理活動摘要 26-2100Z 至 27-2100Z
The geomagnetic field was quiet to active during the past 24 hours.
An initially quiet to unsettled field became unsettled to active
with the onset of a high speed solar wind stream around 1500Z. Solar
wind velocity increased to about 600 km/s and the interplanetary
magnetic field showed fluctuations from about -9 nT to +7 nT.
IIB. 地球物理活動預報
The geomagnetic field is
expected to be mostly active with a chance for isolated minor storm
periods for the next 24 hours (28 April) as the high speed stream is
expected to continue. Unsettled levels with a chance for active
periods is expected for the second day (29 April) and conditions
should decline to mostly unsettled by the third day (30 April).
