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 140 Publicado el 2200Z a las 20 May 2013IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
20/0525Z. There are currently 7 numbered sunspot regions on the disk.
IB. Pronóstico de la actividad solar
Solar activity is likely to be moderate
with a chance for X-class flares on days one, two, and three (21 May, 22
May, 23 May).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
493 km/s at 19/2257Z. Total IMF reached 14 nT at 19/2256Z. The maximum
southward component of Bz reached -5 nT at 20/1953Z. Protons greater
than 10 MeV at geosynchronous orbit reached a peak level of 4 pfu at
19/2255Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (21 May, 22 May)
and unsettled to active levels on day three (23 May). Protons have a
chance of crossing threshold on days one, two, and three (21 May, 22
May, 23 May).
