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 077 Publicado el 2200Z a las 17 Mar 2004IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z Solar activity increased to low levels today. Region
574 (S02E56) showed significant growth in sunspot coverage and
magnetic complexity since yesterday. The dominant central sunspots
appear to be merging to form a small magnetic delta complex. This
region produced multiple B and C-class flares throughout the period.
Region 572 (N19W72) produced a C1 x-ray flare at 17/0931Z with an
associated Type II radio sweep that had an estimated shock velocity
of 1207 km/s. In response to this flare a CME was seen emanating
from the solar northwest limb (on LASCO imagery) which does not
appear to be Earth directed. Region 570 (S14W80) continues to show
a slow, steady decay. Regions 575 (S18W02), 576 (S18W38), and 577
(S01E77) were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels. Region 574 has a small chance of producing an isolated
low-level M-class flare.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron fluxes at geosynchronous orbit reached high
levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels.
