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 084 Issued at 2200Z on 24 Mar 2004IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was low. Occasional C-class events
occurred, as the general level of activity increased. Region 577
(S01W14) generated a C5/Sf flare at 1426 UTC. More recently, an
impulsive C7 limb flare appeared to have its origin from N15E90.
This soon to appear region is showing a hot corona in x-rays
and is also visible in H-alpha. Two new regions were assigned:
Region 580 (S07W07) and Region 581 (S03E81).
IB. Solar Activity Forecast
Solar activity is expected to continue
low. Isolated C-class flares are likely, with a slight chance of an
M-class flare. Watch the northeast limb for the imminent arrival of
a new bright region.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was quiet to mildly unsettled. The greater than
2 MeV electrons at geosynchronous orbit attained high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled through 27 March.
