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 079 Publicado el 2200Z a las 20 Mar 2001IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity has been moderate. Region 9373 (S07W71)
produced two M-class events during the period. The first was a
M1/0f at 20/0218 UTC with an associated Type II radio sweep and a
partial halo CME. The second from this region was an M1/1f at
20/1507 UTC. Region 9384 (N14W74) produced a M1/0f at 20/0333 UTC.
Region 9390 (N14E73) produced a M1/0f at 20/1424 UTC. Three new
regions were numbered today as Region 9388 (N14W49), 9389 (S12E75),
and 9390 (N14E73).
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field ranged from active to severe storm conditions.
A fairly long period of southward turning IMF Bz was observed by the
ACE spacecraft. This activity is likely the result of the CME which
occurred late on 15 March.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active as a result of the recent CME
occurrences.
