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 261 在 17 SEP 2000 上以 2200Z 發行

IA. 太陽活動區域和 16-2100Z到 17-2100Z的活動分析

SOLAR ACTIVITY WAS LOW. THE LARGEST FLARE OF THE PAST DAY WAS A C5/1F AT 17/0643 UTC IN REGION 9167 (N11E69). THIS REGION ALSO PRODUCED A NUMBER OF OTHER LESS SIGNIFICANT SUBFLARES. 9167 IS STILL CLOSE TO THE EAST LIMB BUT APPEARS TO BE A GROWING D-TYPE GROUP. REGION 9165 (N14W26) CONTINUES TO DECAY IN SUNSPOT AREA AND MAGNETIC COMPLEXITY. HOWEVER, IT MANAGED TO PRODUCE SEVERAL C-CLASS SUBFLARES, THE LARGEST OF WHICH WAS A C3/SF AT 17/0042 UTC. REGION 9166 (S14E37) ALSO PRODUCE A FEW C-CLASS FLARES AND CONTINUES TO INCREASE IN COMPLEXITY AS IT ROTATES FURTHER ONTO THE DISK. NEW REGION 9168 (N09E06) EMERGED.
IB. 太陽活動預報
SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. ADDITIONAL C-CLASS ACTIVITY IS EXPECTED IN REGIONS 9165, 9166, AND 9167. M-CLASS FLARES ARE POSSIBLE IN THESE REGIONS AS WELL. IIA. GEOPHYSICAL ACTIVITY SUMMARY 16/2100Z TO 17/2100Z: THE GEOMAGNETIC FIELD RANGED FROM QUIET TO STORM LEVELS. THE FIELD APPEARED TO BE UNDER THE INFLUENCE OF A HIGH-SPEED CORONAL HOLE STREAM FOR MOST OF THE DAY. ACE NEAR-REAL-TIME DATA SUGGESTS THE ARRIVAL OF CME MATERIAL AT L1 AT ABOUT 17/1500 UTC. THIS CME MAY HAVE BEEN ASSOCIATED WITH ACTIVITY IN REGION 9165 ON SEP 15.
IIB. 地球物理活動預報
THE GEOMAGNETIC FIELD IS EXPECTED TO BE UNSETTLED TO ACTIVE, REACHING STORM LEVELS BY SEP 19. THE STRONGEST ACTIVITY IS EXPECTED FROM A CME RELATED TO THE M5/2B FLARE IN REGION 9165 EARLY ON SEP 16. A HIGH-SPEED CORONAL HOLE STREAM MAY MAINTAIN ACTIVITY LEVELS FOR A FEW DAYS AFTER THESE CMES PASS THE EARTH.
