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 199 Publicado el 2200Z a las 18 Jul 2002IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was at high levels. Region 30 (N18W38)
produced an X1/2b flare at 18/0744 UTC with an associated Type II,
Type IV, and discrete frequency radio bursts. SOHO/LASCO imagery
indicates a faint full halo CME. Region 30 continues its gradual
decay but retains a beta-gamma-delta magnetic classification.
Region 36 (S07E37) has grown to 860 millionths and 26 spots. This
large compact region did not produce any significant activity during
the last 24 hours.
IB. Pronóstico de la actividad solar
Solar activity is expected to be
moderate. M-Class activity is expected from Region 30 and Region
36. There is also the possibility of isolated X-class activity from
these regions.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was at quiet to unsettled levels. The PCA
event that began on 16/2215 UTC ended at 18/0300 UTC with a peak
absorption observed on the Thule 30 MHz riometer of 6 Db at 17/1600
UTC. The greater than 10 MeV proton event that began on 16/1750 UTC
ended at 18/1550 UTC, peak value reached 234 pfu at 17/1600 UTC.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to active. A CME shock from the X1 event on
18/0744 UTC is expected to arrive early on day two of the forecast
period.
