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 008 Issued at 2200Z on 08 JAN 2000IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT OF THE DAY
WAS A C-6 AT 1645Z. AN ERUPTIVE PROMINENCE AT S54E90, BRIGHT PLAGE
IN NEWLY ASSIGNED REGION 8823 (S31E63) AND REGION 8819 (N10W52), AS
WELL AS ENHANCED PLAGE NEAR S11E75 WERE ALL OCCURRING WHEN THESE
X-RAYS WERE RECORDED. LIMB ACTIVITY HAS BEEN COMMONPLACE ON THE EAST
LIMB AS A PRECURSOR OF ADDITIONAL ACTIVE CENTERS TO APPEAR. THE
REMAINING DISK REGIONS WERE QUIET AND EITHER STABLE OR DECAYING.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO CONTINUE
LOW.
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS HIGH.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED, WITH AN INCREASING CHANCE OF ACTIVE
PERIODS AT THE END OF THE INTERVAL. A WELL-DEFINED CORONAL HOLE IS
NOW JUST WEST OF CENTRAL MERIDIAN.
