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 295 Publicado el 2200Z a las 21 Oct 2012IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been moderate for the past 24 hours.
An M1/Sf flare from Region 1598 (S12E70) occurred at 21/2003Z.
This region has shown some development as it has rotated further
onto the visible disk and remains the main area of interest. Region
1596 (N07E33) continues to be the most magnetically complex region
on the visible disk as an Eho/Beta-Gamma spot group, but has shown
slight decay in the trailer spots over the past 24 hours. All other
spots remain relatively stable. No Earth-directed CMEs were
observed over the past 24 hours.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
for the next three days (22-24 October) with isolated M-class flares
likely.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was quiet over the past 24 hours. Solar wind
speed, as measured by the ACE spacecraft, remained steady at
approximately 360 km/s while the Bz component of the interplanetary
magnetic field showed minor deviations of +/-4 nT. The greater than
2 MeV electron flux at geosynchronous orbit was at high levels
throughout the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled on days 1 and 2 (22-23 October)
due to the effects of a coronal hole high speed stream (CH HSS).
Conditions are expected to return to quiet levels by day 3 (24
October) as the effects from the CH HSS begin to wane.
