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 362 publicerat klockan 2200Z på 28 DEC 1999IA. Analys av solfläcksgrupper och solaktivitet från 27-2100Z till 28-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8806 (N20W65)
PRODUCED AN M4/2B FLARE AT 28/0039UT. THIS EVENT WAS ACCOMPANIED BY
MODERATE RADIO EMISSIONS, INCLUDING A TYPE II SWEEP. REGION 8806
CONTINUES TO DECLINE AS IT APPROACHES THE WEST LIMB. ONLY MINOR
ACTIVITY WAS OBSERVED IN THE OTHER THREE SPOTTED REGIONS. THE
PROMINENCE THAT ERUPTED AROUND 27/2100UT APPEARS IN THE SOHO IMAGERY
TO COVER MUCH OF THE NORTHERN POLAR AREA.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE.
IIA. Sammanfattning av geofysisk aktivitet 27-2100Z till 28-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET. A SHORT PERIOD OF UNSETTLED
CONDITIONS WAS OBSERVED AROUND 0300UT. THERE WERE ONLY MINOR
PARTICLE ENHANCEMENTS FOLLOWING THE 28/0039UT M4/2B FLARE.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED EARLY IN THE PERIOD. THE FIELD IS
EXPECTED TO BECOME DISTURBED STARTING ON 31 DEC AS A RESULT OF A
LARGE EQUATORIAL CORONAL HOLE EAST OF CENTRAL MERIDIAN.
