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 062 Issued at 2200Z on 02 MAR 2000

IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z

SOLAR ACTIVITY HAS BEEN HIGH. AN IMPULSIVE CLASS X1 FLARE OCCURRED IN REGION 8882 (S15W58) BEGINNING AT 02/0828Z FOLLOWED BY A CLASS M5 EVENT IN THE SAME REGION BEGINNING AT 02/1335Z. TYPE II RADIO BURSTS OCCURRED IN CONJUNCTION WITH BOTH EVENTS. BOTH EVENTS PRODUCED ONLY LOW TO MODERATE TOTAL ENERGY IN TERMS OF THEIR RADIO AND X-RAY BURSTS AND THEIR DURATION. IMPRESSIVE CORONAL MASS EJECTIONS OVER THE SOUTHWEST LIMB OF THE SUN FOLLOWED BOTH FLARES. THE LATER CME WAS FOLLOWED BY FURTHER EJECTION OVER THE FAR SOUTHEAST LIMB. REGION 8882 AND REGION 8891 (S15W04) REMAIN COMPLEX AND POTENTIAL SOURCES OF MAJOR FLARES. THE SUN APPEARS TO BE IN AN UNSETTLED MODE. MINOR SHORT-LIVED SUNSPOT GROUPS ARE APPEARING AT VARIOUS LOCATIONS ON THE DISK AND SMALL FLARES ARE OCCURRING IN MANY OF THE ACTIVE REGIONS.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO REMAIN MODERATE TO HIGH. CLASS M EVENTS ARE EXPECTED AND THERE IS A CHANCE OF MORE CLASS X EVENTS.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
THE GEOMAGNETIC FIELD HAS BEEN UNSETTLED TO ACTIVE. THERE WAS A VERY SMALL ENHANCEMENT OF ENERGETIC PROTONS GREATER THAN 10 MEV MEASURED BY GOES FOLLOWING THE CLASS X EVENT EARLIER TODAY. ENERGETIC ELECTRONS GREATER THAN 2 MEV AS MEASURED BY GOES AT GEOSYNCHRONOUS ORBIT HAVE REMAINED BELOW ALERT THRESHOLDS TODAY.
IIB. Geophysical Activity Forecast
THE POTENTIAL FOR GEOMAGNETIC STORMS IS UNCLEAR. THE CORONAL MASS EJECTIONS DO NOT APPEAR TO BE PRIMARILY EARTH-DIRECTED, BUT THEY MAY HAVE AT LEAST A MODERATE IMPACT IN TERMS OF GEOMAGNETIC ACTIVITY. THE FORECAST IS FOR ACTIVE CONDITIONS WITH A CHANCE OF A MINOR TO MAJOR STORM. THERE IS A CHANCE OF ANOTHER INCREASE IN ENERGETIC PARTICLES DURING THE FORECAST PERIOD AS A RESULT OF THE PASSAGE OF SHOCKS FROM THE CME TODAY.
