Solaktivitetsrapport
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 266 publicerat klockan 2200Z på 23 SEP 1999IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT OF THE PERIOD
WAS AN IMPULSIVE C1/SF FROM 8706 (N20E25). REGION 8700 (N12W61) WAS
THE MOST ACTIVE REGION THIS PERIOD AND PRODUCED SEVERAL MINOR
SUBFLARES. A SIXTEEN DEGREE FILAMENT ERUPTED FROM NEAR S14W47 AT
23/1529Z. REMAINING REGIONS WERE MOSTLY QUIET.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN
AT LOW LEVELS. ONLY ISOLATED C-CLASS X-RAY EVENTS ARE EXPECTED.
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO MAJOR STORM LEVELS. THE
GEOMAGNETIC STORM THAT FOLLOWED YESTERDAY'S SUDDEN IMPULSE AT
22/1222Z, CONTINUED THROUGH EARLY THIS PERIOD. THE STORM SUBSIDED
RATHER QUICKLY AFTER 23/0600Z AND THE FIELD HAS BEEN MOSTLY QUIET TO
UNSETTLED SINCE.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT QUIET TO ACTIVE LEVELS. SOLAR WIND SPEED REMAINS
ELEVATED FOLLOWING YESTERDAY'S INTERPLANETARY SHOCK. OCCASIONAL
ACTIVE PERIODS ARE LIKELY DURING LOCAL NIGHTTIME HOURS ESPECIALLY AT
HIGHER LATITUDES.
