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 002 Issued at 2200Z on 02 JAN 2000

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

SOLAR ACTIVITY WAS LOW. A SINGLE MINOR OPTICALLY UNCORRELATED C1 EVENT OCCURRED AT 01/2245Z. ONLY FOUR MOSTLY STABLE SUNSPOT GROUPS ARE VISIBLE NOW WITH NO OBVIOUS COMPLEXITY EVIDENT. A LARGE 22 DEGREE FILAMENT DISAPPEARED FROM NEAR S28W03.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE LOW. ISOLATED MINOR C-CLASS EVENTS ARE POSSIBLE.
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. DISTURBED CONDITIONS FROM THE CORONAL HOLE HIGH SPEED STREAM THAT BEGAN ON 30 DEC, CONTINUED THIS PERIOD. THE GREATER THAN TWO MEV ELECTRON FLUX WAS AT MODERATE TO HIGH LEVELS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO CONTINUE AT QUIET TO ACTIVE LEVELS WITH OCCASIONAL MINOR STORM PERIODS AT HIGH LATITUDES. THIS CORONAL HOLE RELATED DISTURBANCE WILL BEGIN TO SUBSIDE BY DAY TWO. QUIET TO UNSETTLED CONDITIONS SHOULD PREVAIL BY DAY THREE.
