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 230 publicerat klockan 2200Z på 17 AUG 2000IA. Analys av solfläcksgrupper och solaktivitet från 16-2100Z till 17-2100Z SOLAR ACTIVITY WAS LOW. OCCASIONAL ISOLATED C-CLASS
EVENTS OCCURRED DURING THE PERIOD. THE LARGEST EVENT WAS A C4/1N AT
17/0837UT FROM REGION 9131 (N14E21). REGION 9125 (N26W22) REMAINS
THE LARGEST AND MOST MAGNETICALLY COMPLEX GROUP OF THE 12 SPOTTED
REGIONS VISIBLE. REGION 9125 PRODUCED A C1/SF AT 17/1241UT. OVERALL
MOST OF THE REGIONS WERE RELATIVELY STABLE AND PRODUCED VERY LITTLE
ACTIVITY. ONE NEW REGION WAS NUMBERED: 9136 (N07W06).
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO CONTINUE
TO BE LOW WITH AN ISOLATED CHANCE OF AN M-CLASS EVENT.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 16/2100Z TO 17/2100Z:
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT REACHED MODERATE LEVELS AT
APPROXIMATELY 17/0900UT AND STAYED AT MODERATE LEVELS FOR THE REST
OF THE PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
