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 206 Publicado el 2200Z a las 25 Jul 2002IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity has been low. Region 39 (S16E34)
produced a long duration C2 at 25/0921 UTC which was observed in the
SOHO EIT imagery. Region 39 continues to maintain a magnetic delta
configuration. Region 36 (S07W54) continues to produce C-class
events and retains its beta-gamma magnetic structure. A new region
was numbered today as Region 47 (N07W48).
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. A major flare is possible from Regions 36 and 39.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic field has been quiet to unsettled. A weak shock
passed the ACE spacecraft at 25/1300 UTC. This shock is believed
related to the full halo CME on 23 July. The level of disturbance
in the geomagnetic field following the shock was below expectation.
The greater than 10 MeV proton event that started 22/0655 UTC is
still in progress with the tentative maximum of 28 pfu at 23/1025
UTC. The energetic electron fluxes at geosynchronous orbit were at
high levels today.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled. Isolated active periods are
possible due to the activity over the past several days. The
greater than 10 MeV proton event is expected to continue for the
next 24 hours. The energetic electron fluxes at geosynchronous
orbit are expected to remain at high levels for the next several
days.
