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 112 Publicado el 2200Z a las 22 Apr 2002IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z Solar activity decreased to low levels. Region 9906
(S14W103), now well beyond the west limb, produced a C7 X-ray flare
at 22/0019 UTC associated with a bright surge and an eruptive
prominence. Region 9912 (N10W25) produced a C2/Sf flare at 22/1210
UTC associated with a Type II radio sweep (estimated velocity 804
km/sec). Region 9912 was in a gradual growth phase. A weak magnetic
delta configuration may have developed within its trailer spots. New
Region 9917 (S30E45) was numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low to moderate levels. There's a chance for an isolated M-class
flare from Region 9912.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
Geomagnetic field activity ranged from quiet to active levels. Active
levels occurred during 22/0300 - 0600 UTC. The greater than 100 MeV
proton event that began at 21/0155 UTC reached a peak of 22.9 pfu at
21/1025 UTC and was in progress as the period ended. The greater
than 10 MeV proton event that began at 21/0225 UTC reached a peak of
2520 pfu at 21/2320 UTC and was in progress as the period ended.
Peak polar cap absorption associated with the proton event was
estimated to be 16 dB (daytime) and 3.9 dB (nighttime).
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to increase to active to minor storm levels on 23 April in
response to yesterday's X1/partial-halo CME event. Unsettled to
active conditions are expected on 24 April as the disturbance winds
down. Unsettled conditions are expected on the final day. The
greater than 100 MeV proton event is expected to end early on 23
April. The greater than 10 MeV proton event is expected to end on 24
April.
