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 032 Publicado el 2200Z a las 01 Feb 2003IA. Análisis de regiones solares activas y de actividad desde 31-2100Z hasta 01-2100Z Solar activity was moderate during the past 24 hours.
All of today's flare activity was dominated by new Region 276
(S14E76), which produced an M1 at 0905 UTC, a C9/Sf at 1954 UTC, as
well as numerous additional C-class subflares. Observations of the
group so far indicate a relatively small (190 millionths) D-type
sunspot group. An erupting prominence was observed at 31/2200 UTC on
the Northwest limb and was associated with a type II sweep (shock
velocity 500 km/s) and a CME seen by LASCO. The remainder of the
regions on the disk were quiet and stable.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
to moderate. Region 276 is expected to be the main driver of
activity, and has a fair chance for producing an additional M-class
event over the next three days.
IIA. Resumen de la actividad geofísica 31-2100Z a 01-2100Z
The geomagnetic field ranged from quiet to active levels during the
past 24 hours. Quiet conditions prevailed for most of the day, but
an increase to unsettled to active began at 1500 UTC. A marked
increase in solar wind velocity and total magnetic field strength
was observed beginning at 1300 UTC, but a predominantly positive
value for Bz suppressed activity until 1900 UTC, when Bz turned
weakly southwards. The interpretation of the enhanced solar wind
flow is not obvious, but seems most consistent with the passage of
transient flow due to the halo CME that occurred on 30 January. The
great than 2 MeV electron fluxes reached high levels during the past
24 hours.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly active for the next 24 hours with a chance for
some isolated minor storm periods. Conditions should subside to
unsettled to active by day two, and return to mostly unsettled
levels by the third day.
