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 148 Publicado el 2200Z a las 28 May 2002IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity was at low levels. Region 9957 (N12W86)
produced a C3/Sf flare at 28/1635 UTC. This region remains active
as it transits the west limb. Three new regions were numbered
today: Region 9971 (N21E00), Region 9972 (S26E56) and Region 9973
(S16E73). Region 9973 produced a number of minor C-class flares and
currently is the largest spot on the disk with an area of 420
millionths. An impressive halo CME was observed in SOHO/LASCO C2
imagery at 28/1626 UTC. However this CME appears to have a backside
source.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. Region 9961 and 9963 have the potential for isolated
M-class events.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic field was at quiet to unsettled levels. ACE solar
wind data indicated a continued gradual decay in velocity to
approximately 600 km/s.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels. Isolated active
conditions are possible on day one of the forecast period.
