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 111 Publicado el 2200Z a las 21 Apr 2015IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been at high levels for the past 24 hours.
The largest solar event of the period was a M4 event observed at
21/1545Z from Region 2322 (N11W87). There are currently 9 numbered
sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (22 Apr, 23 Apr,
24 Apr).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic
field has been at unsettled to active levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 628 km/s at 21/0632Z. Total IMF reached 14 nT at 20/2127Z. The
maximum southward component of Bz reached -7 nT at 21/0249Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 1433
pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (22 Apr), quiet to
active levels on day two (23 Apr) and quiet levels on day three (24
Apr).
