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 110 Publicado el 2200Z a las 20 Apr 2013IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
20/0036Z. There are currently 6 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be low with a
chance for an M-class flare on all three days (21-23 Apr).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft remained around 300km/s. Total IMF
reached 6 nT at 20/1925Z. The maximum southward component of Bz reached
-4 nT at 20/1039Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 116 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet levels on day one (21 Apr), quiet to unsettled levels on
day two (22 Apr) and quiet to active levels on day three (23 Apr).
