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 014 Issued at 2200Z on 14 Jan 2004IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity has been low. Region 536 (S12, L=74),
produced a C1 flare at 14/1602 UTC. No new regions were numbered
today.
IB. Solar Activity Forecast
Solar activity is expected to be low.
Region 537 may produce C-class and isolated M-class flares.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field has been quiet to active.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled conditions. Activity may
increase to active to minor storm conditions on 17 January due to
increased solar wind speeds from a coronal hole moving into
geoeffective position.
