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.

SDF Número 111 Publicado el 2200Z a las 21 Apr 2017IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 3 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very low
with a chance for a C-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

Solar wind speed reached a peak of 691 km/s at 21/2050Z. Total IMF
reached 14 nT at 21/1613Z. The maximum southward component of Bz reached
-12 nT at 21/1635Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 2805 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (22 Apr), active to major
storm levels on day two (23 Apr) and active to minor storm levels on day
three (24 Apr).
