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 048 Publicado el 2200Z a las 17 Feb 2002IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity remained at low levels. Region 9830
(S18E31) was the most active of the visible regions. It produced
occasional subflares as it grew at a gradual pace with increased
sunspot area and magnetic complexity. A magnetic delta configuration
may have developed within its leader spots. Region 9825 (N12W35)
continued to gradually decay and simplify. The remaining active
regions were unremarkable.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low to moderate levels. There is a chance for an isolated M-class
flare from Region 9830.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
Geomagnetic field activity was at quiet to active levels. Activity
increased to unsettled to active levels during 17/0300 - 0900 UTC
following a sudden impulse at 17/0257 UTC (13 nT, as measured by the
Boulder USGS magnetometer). Field activity decreased to quiet to
unsettled levels after 17/0900 UTC. This brief increase in activity
appeared to be the result of a weak CME passage.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to be at quiet to unsettled levels.
