Solaktivitetsrapport

Föregående rotation Föregående dag Kalender
Nästa dag Nästa rotation
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

USAF/NOAA rapport för sol- och geofysisk aktivitet

SDF Nummer 308 publicerat klockan 2200Z på 04 NOV 1998

IA. Analys av solfläcksgrupper och solaktivitet från 03-2100Z till 04-2100Z

SOLAR ACTIVITY WAS LOW. OVERALL THE AMOUNT OF ACTIVITY HAS INCREASED APPRECIABLY SINCE YESTERDAY. REGION 8375 (N18W07) HAS BEEN THE MOST ACTIVE REGION PRODUCING SIX C-CLASS FLARES AS WELL AS SEVERAL OPTICAL SUBFLARES AND ONE 1N OPTICAL FLARE. A FULL HALO CME WAS OBSERVED BY THE LASCO/SOHO SATELLITE AT 04/0418UT. THIS WAS IN CONJUNCTION WITH A C5/SF PRODUCED BY REGION 8375. REGION 8375 IS THE LARGEST AND MOST COMPLEX REGION ON THE SUN. CURRENTLY A DAI, BETA-GAMMA SPOT GROUP. THIS REGION HAS INCREASED SLIGHTLY IN SIZE AND THE SPOT COUNT HAS INCREASED FROM 22 TO 28. OTHER ACTIVE REGIONS ARE 8376 (S27E15), 8378 (N14E63) AND 8379 (S18W28) ALL OF WHICH PRODUCED AN OPTICAL SUBFLARE. REGION 8379 IS A NEW NUMBERED REGION WITH A 5 SPOT CRO, BETA SPOT GROUP. ONE OTHER REGION WAS NUMBERED: 8380 (S20E65) WITH AN AXX, ALPHA SPOT.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN LOW WITH POSSIBLE ISOLATED M-CLASS FLARING FROM REGION 8375.
IIA. Sammanfattning av geofysisk aktivitet 03-2100Z till 04-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED WITH POSSIBLE ACTIVE PERIODS. THE CAUSE FOR THE POTENTIAL INCREASE IN GEOMAGNETIC ACTIVITY IS DUE TO A PARTIAL HALO CME THAT WAS OBSERVED BY THE LASCO/SOHO SATELLITE ON 02/1354UT. THIS WAS IN CONJUNCTION WITH A C1/N1 FLARE IN REGION 8376 LOCATED AT S25E44 AT THAT TIME. THE FULL HALO CME OBSERVED TODAY AT 04/0418UT COULD POSSIBLY CAUSE GEOMAGNETIC ACTIVITY LATE ON NOVEMBER 6TH OR ON NOVEMBER 7TH.
