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 165 Issued at 2200Z on 14 Jun 2002IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was at low levels. Three new regions
were numbered today: Region 9999 (S05W61), Region 0000 (N18E50),
and Region 1 (N20E70). Please refer to the attached plain message
for a region numbering discussion. Region 9987 (S16W86) produced a
C1 flare at 14/1020 UTC. Region 9991(S21W21) has remained
relatively stable. New Region 1 has shown some surging but due its
limb proximity prevents a complete analysis.
IB. Solar Activity Forecast
Solar activity is expected to be low.
Region 9987 and 9991 have the potential of C- and low level M-class
events. Old Region 9963 (N17, L= 318) is due to return on day two
of the forecast period.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be a quiet to unsettled levels. Isolated active
conditions are possible on day one of the forecast period due to
coronal hole effects.
