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 123 publicerat klockan 2200Z på 03 MAY 1999IA. Analys av solfläcksgrupper och solaktivitet från 02-2100Z till 03-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8525 (N18E24)
GENERATED AN M4/2N EVENT AT 0602Z. A HALO CORONAL MASS EJECTION WAS
SEEN BY SOHO-LASCO A SHORT TIME LATER. THE ACTIVITY INCLUDED TYPE II
AND IV SWEEPS, AND A RADIO BURST OF 220 SFU AT 2695 MHZ. THE REGION
HAS BEEN LARGELY QUIET SINCE THIS ACTIVITY, RETAINING ITS BRIGHT
PLAGE AND OMINOUS APPEARANCE. REGION 8524 (N20W69) BECAME ACTIVE
LATE IN THE DAY, PRODUCING THREE C-CLASS FLARES IN THE LATTER HALF
OF THE PERIOD. THE REMAINDER OF THE DISK AND LIMBS WERE QUIET.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGIONS 8524 AND 8525 ARE LIKELY TO PRODUCE CONTINUED
C-CLASS ACTIVITY. AN ISOLATED M-LEVEL EVENT MAY OCCUR IN THE NEXT 72
HOURS.
IIA. Sammanfattning av geofysisk aktivitet 02-2100Z till 03-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRONS AT GEOSYNCHRONOUS WERE AT HIGH LEVELS THE MAJORITY OF THE
DAY.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED THROUGHOUT THE PERIOD. ACTIVITY FROM
TODAY'S HALO CME IS NOT ANTICIPATED IN THE NEXT THREE DAYS.
