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 141 Publicado el 2200Z a las 21 May 2013IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z 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
21/0012Z from Region 1751 (S23W57). There are currently 7 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 and a slight chance for an X-class flare on
days one, two, and three (22 May, 23 May, 24 May).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 570 km/s at
21/1900Z. Total IMF reached 6 nT at 21/1855Z. The maximum southward
component of Bz reached -5 nT at 21/0515Z. Protons greater than 10 MeV
at geosynchronous orbit reached a peak level of 2 pfu at 20/2145Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (22 May, 24
May) and unsettled to active levels on day two (23 May). Protons have a
slight chance of crossing threshold on days one, two, and three (22 May,
23 May, 24 May).
