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 178 publicerat klockan 2200Z på 26 JUN 2000IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z SOLAR ACTIVITY DECREASED TO LOW LEVELS. OCCASIONAL,
MOSTLY LOW-LEVEL C-CLASS SUBFLARES OCCURRED, MOST OF WHICH WERE
PRODUCED BY REGION 9054 (N12W18). THIS REGION IS A MEDIUM-SIZED,
MIXED-POLARITY (BETA-GAMMA) GROUP THAT HAS GRADUALLY DEVELOPED
DURING THE LAST FEW DAYS. IT WAS THE LIKELY SOURCE (BASED ON
SOHO/EIT IMAGES) FOR A C4 X-RAY FLARE AT 26/0157Z ASSOCIATED WITH A
WEAK TYPE II RADIO SWEEP (EST. SHOCK VELOCITY 800 KM/SEC) AND A
POSSIBLE PARTIAL-HALO CME. REGIONS 9046 (N20W75) AND 9049 (N16W09)
DECAYED SLIGHTLY, WHILE THE REMAINING REGIONS WERE STABLE. NEW
REGION 9063 (N24E41) WAS NUMBERED.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE AT
LOW TO MODERATE LEVELS. OCCASIONAL C-CLASS SUBFLARES ARE EXPECTED.
REGION 9054 APPEARS CAPABLE OF PRODUCING AN ISOLATED M-CLASS FLARE.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
GEOMAGNETIC FIELD ACTIVITY INCREASED TO UNSETTLED TO ACTIVE LEVELS
WITH BRIEF MINOR TO MAJOR STORM PERIODS AT HIGH LATITUDES.
IIB. Prognos för geofysisk aktivitet
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO REMAIN AT UNSETTLED TO ACTIVE LEVELS DURING 27 - 28 JUNE
WITH BRIEF STORM LEVELS POSSIBLE AT HIGH LATITUDES. FIELD ACTIVITY
IS EXPECTED TO DECLINE TO QUIET TO UNSETTLED LEVELS DURING THE LAST
DAY OF THE PERIOD. THE GREATER THAN 2 MEV ELECTRON FLUX AT
GEOSYNCHRONOUS ORBIT IS EXPECTED TO INCREASE TO MODERATE TO HIGH
LEVELS DURING THE PERIOD.
