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 79 Publicado el 2200Z a las 20 Mar 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 C5 event observed at
20/0102Z from Region 1698 (S19, L=119). There are currently 5 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low with
a slight chance for an M-class flare on day one (21 Mar) and likely to
be low with a slight chance for an M-class flare on day two (22 Mar) and
expected to be very low with a chance for a C-class flares on day three
(23 Mar).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
711 km/s at 20/1711Z. Total IMF reached 11 nT at 20/1858Z. The maximum
southward component of Bz reached -7 nT at 20/1453Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1516 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to active levels on day one (21 Mar) and quiet to
unsettled levels on days two and three (22 Mar, 23 Mar).
