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 057 Issued at 2200Z on 26 Feb 2001IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity was low. An optically uncorrelated C1
x-ray flare occurred at 26/0741 UTC. The probable source for this
event was observed by SOHO/LASCO from behind the west limb.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was quiet to unsettled. An isolated period of
active conditions occurred at 26/1800 UTC. A slight proton
enhancement was observed which was probably associated with the
event which occurred behind the limb earlier today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled for the forecast period.
