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 175 Issued at 2200Z on 24 Jun 2002IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was low during the past 24 hours.
Today's only C-flare was a C1 at 1606 UTC. The optical source was
not obvious, but there were some slightly enhanced loops visible in
EIT 195 from Region 5 (N14W29). New Region 15 (S27E39) emerged and
was assigned today. A 13 degree filament near N40W06 disappeared
sometime between 0112 UTC and 1345 UTC. A CME erupted from the west
limb at 24/0054 UTC but did not have any earthward component. Region
8 (S10W01) continues to be the largest region on the disk and
appeared to be growing and developing some magnetic complexity
during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be low
for the next three days. There is a very slight chance for moderate
activity from Region 8.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled for the next three days.
