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 275 publicerat klockan 2200Z på 02 OCT 1999IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z SOLAR ACTIVITY WAS LOW. NUMEROUS MINOR C-CLASS X-RAY
EVENTS OCCURRED WITH NO OPTICAL CORRELATION EXCEPT WITH A C3/SF
OBSERVED AT 02/1828Z FROM REGION 8716 (N21E70). THE LARGEST EVENT
WAS A C6 AT 02/0156Z. SURGING WAS OBSERVED FROM THE NORTHEAST AND
SOUTHEAST LIMB AS TWO ACTIVE REGIONS ARE STARTING TO ROTATE ONTO THE
DISK. NEW REGION 8716 (N21E70) WAS NUMBERED.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
WITH A SLIGHT CHANCE OF AN M-CLASS X-RAY EVENT MOST LIKELY OCCURRING
FROM ONE OF THE MORE ACTIVE REGIONS NEAR THE EAST LIMB.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT ALTERNATED BETWEEN MODERATE TO
HIGH LEVELS THROUGHOUT THE PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO ACTIVE DURING THE FIRST DAY OF THE PERIOD
THEN BECOMING MORE QUIET TO UNSETTLED. ISOLATED ACTIVE CONDITIONS
ARE MORE LIKELY TO OCCUR IN THE HIGHER LATITUDES DURING THE FIRST
DAY OF THE PERIOD.
