Solar activity report

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.

Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 157 Issued at 2200Z on 05 JUN 2000

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

SOLAR ACTIVITY WAS MODERATE. THREE SIGNIFICANT FLARES WERE OBSERVED FROM THREE DIFFERENT REGIONS. THE FIRST AND LARGEST WAS AN M3 X-RAY EVENT WITH ACCOMPANYING TENFLARE FROM REGION 9026 (N20E23). THIS REGION IS BY FAR THE LARGEST AND MOST COMPLEX REGION ON THE VISIBLE DISK WITH OVER 800 MILLIONTHS OF WHITE LIGHT AREA IN AN "E" TYPE BETA-GAMMA-DELTA CONFIGURATION. REGION 9024 (S11W45) PRODUCED A C4/1F FLARE WITH TYPE II AND IV RADIO SWEEPS AT 05/0325Z. THERE IS NO NOTEWORTHY MAGNETIC COMPLEXITY OBVIOUS IN THIS REGION WHICH APPEARS TO BE IN DECAY. AN M1/1F FLARE ERUPTED FROM REGION 9031 (S32W52) AT 05/1359Z. ONLY MINOR GROWTH NOTED IN THIS REGION. NEW REGIONS 9032 (S18E41) AND 9033 (N24E77) WERE NUMBERED TODAY.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE AT MODERATE TO HIGH LEVELS. REGION 9026 WILL LIKELY PRODUCE M-CLASS FLARES WITH AN ISOLATED CHANCE OF AN X-CLASS FLARE.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
THE GEOMAGNETIC FIELD WAS UNSETTLED TO ACTIVE WITH ISOLATED MINOR STORMING CONDITIONS AT HIGH LATITUDES. THESE DISTURBED CONDITIONS FOLLOWED THE SUDDEN IMPULSE OBSERVED AT 04/1500Z.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO CONTINUE AT UNSETTLED TO ACTIVE CONDITIONS THROUGH DAY ONE. MOSTLY QUIET TO UNSETTLED LEVELS ARE EXPECTED ON DAY TWO. UNSETTLED WITH OCCASIONAL ACTIVE PERIODS ARE LIKELY ON DAY THREE DUE TO A FAVORABLY POSITIONED CORONAL HOLE AND THE POSSIBILITY OF EFFECTS FROM THIS MORNING'S C4/CME AT 05/0325Z.
