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 024 Issued at 2200Z on 24 Jan 2002

IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z

Solar activity was low. The largest flare of the past day was a long-duration C7 at 24/0439 UTC. Images from the SOHO spacecraft suggest that the source of the event was from just behind the east limb. Other areas only produced a few small subflares.
IB. Solar Activity Forecast
Solar activity is expected to be low to moderate. An isolated M-class flare is possible in Regions 9787 (S06W06) or 9788 (N18W30).
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled.
