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。

美國空軍/美國國家海洋暨大氣總署太陽與地球物理活動聯合報告

SDF 編號 224 在 11 AUG 2000 上以 2200Z 發行

IA. 太陽活動區域和 10-2100Z到 11-2100Z的活動分析

SOLAR ACTIVITY WAS LOW. FREQUENT C-CLASS FLARES OCCURRED, WITH FIVE REGIONS PARTICIPATING. REGION 9114 (N11W45) IS STILL THE MOST IMPRESSIVE IN WHITE LIGHT AND H-ALPHA. NEWLY NUMBERED REGIONS 9126 (N06W41) AND 9127 (S40E20) EACH HAD SUBFLARES. REGIONS 9124 (S14E52) AND 9125 (N25E55) WERE ACTIVE THROUGHOUT THE DAY.
IB. 太陽活動預報
SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. IIA. GEOPHYSICAL ACTIVITY SUMMARY 10/2100Z TO 11/2100Z: THE GEOMAGNETIC FIELD WAS AT UNSETTLED TO SEVERE STORM LEVELS. A PROLONGED PERIOD OF STEADY SOUTHWARD IMF LASTING MORE THAN 24 HOURS FUELED THE DISTURBANCE. THE BZ MAGNITUDE WAS NEARLY CONSTANT NEAR 10 NT. AT APPROXIMATELY 1800Z, A SHOCK PASSED ACE AND ENDED THE NEAR STEADY-STATE OF THE SOLAR WIND. THE SOLAR WIND SPEED AND DENSITY WERE QUITE AVERAGE PRIOR TO THE SHOCK, BUT ATTAINED VALUES NEAR 600 KM/S, AND 10 P/CC AFTER. THIS TRANSIENT MAY BE RELATED TO THE HALO CME OF 09 AUGUST. A SATELLITE PROTON EVENT AT GREATER THAN 10 MEV BEGAN AT 1650Z. THIS VERY SMALL EVENT REACHED A MAXIMUM OF 17 PFU AT 1655Z AND ENDED AT 1740Z. A SMALL PCA OF APPROXIMATELY 2.0 DB OCCURRED AT THULE CONCURRENT WITH THE PROTON EVENT. THE SOLAR SOURCE OF THE PARTICLES IS AS YET UNDETERMINED. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT ATTAINED HIGH LEVELS LATE IN THE PERIOD.
IIB. 地球物理活動預報
THE GEOMAGNETIC FIELD IS EXPECTED TO BE AT ACTIVE TO MINOR STORM LEVELS FOR THE NEXT THREE DAYS. EFFECTS FROM TODAY'S SHOCK, IN CONJUNCTION WITH THE PRE-EXISTING AND STILL CONTINUING SOUTHWARD IMF, SHOULD FURTHER EXTEND THE CURRENT DISTURBANCE. LOCAL NIGHTTIMES SHOULD SEE THE PERIODS OF THE STRONGEST ACTIVITY.
