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 078 Publicado el 2200Z a las 19 Mar 2002IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was moderate. Region 9866 (S10W59)
produced a long duration M1/1f flare at 19/1144 UTC. Two partial
halo CMEs in rapid succession occurred along with this event, with
an estimated plane of sky speed for the combined ejecta in the range
of 700-750 km/s. Region 9866 has simplified to a beta-gamma
magnetic configuration. Two new regions were numbered today:
Region 9874 (N18E21) and Region 9875 (S18E63).
IB. Pronóstico de la actividad solar
Solar activity is expected to be
moderate. Region 9866 and Region 9871 have the potential for
M-class events. There is a slight possibility for an isolated
X-class or proton event.
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was at quiet to minor storm levels Minor storm
levels were observed early in the day, due to a three hour period of
sustained southward Bz during 0200-0500 UTC. The greater than 10
MeV proton event remains in progress, with a maximum flux of 53 pfu
observed at 19/0650 UTC.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to active. Active conditions are expected on
day one from effects of the CME on 18 March. Activity is expected
to subside during day two. By day three, effects from the CME
activity discussed in section 1A above are expected to result in
predominantly active conditions.
