Informe actividad solar
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.

Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 043 Publicado el 2200Z a las 12 Feb 2003IA. Análisis de regiones solares activas y de actividad desde 11-2100Z hasta 12-2100Z Solar activity remained at low levels. The most
significant activity during the period was a C8.7/1f that occurred
at 12/0151Z from Region 280 (S06W55). A Type II radio sweep was
associated with this event that had an estimated shock velocity of
632 km/s. LASCO imagery depicted a narrow CME and further analysis
indicates there is little chance of it becoming geoeffective.
Region 282 (N10W32) contributed to the day's activity with lesser B
and C-class flare activity. Few changes were observed in the
remaining small and magnetically simple regions. No new regions
were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels.
IIA. Resumen de la actividad geofísica 11-2100Z a 12-2100Z
The geomagnetic field was at quiet to unsettled levels. A single
isolated active period was observed at higher latitudes between
12/1500 to 1800Z. The greater than 2 MeV electron fluxes at
geosynchronous orbit reached high levels again today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled. Day three may experience
isolated active periods due to an anticipated favorably positioned
transequatorial coronal hole.
