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 338 Publicado el 2200Z a las 04 Dec 2002IA. Análisis de regiones solares activas y de actividad desde 03-2100Z hasta 04-2100Z Solar activity fell to very low levels. The largest
optically correlated event of the period was a B8/Sf flare from
Region 212 (N13E49) at 04/1632 UTC. Regions 207 (S19W21) and 208
(N10E08) also produced B-class flares. Region 208 retains some
magnetic complexity with mixed polarity in its leading spots. No
new regions were numbered today.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
at very low to low levels for the early part of the forecast period,
with a slight chance for isolated moderate flare activity. Old
Region 191 (S18, L=203) is expected to return by 05 December, and
may increase the chance for moderate flare activity by the end of
the forecast period.
IIA. Resumen de la actividad geofísica 03-2100Z a 04-2100Z
The geomagnetic field was quiet to unsettled, with an isolated active
period observed at high latitudes during 04/1500-1800 UTC. High
flux values for greater than 2 MeV electrons at geosynchronous orbit
were observed again for the sixth consecutive day.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled, trending toward active conditions
by the end of the forecast period, due to the rotation of a
trans-equatorial coronal hole into geo-effective heliographic
longitudes. The greater than 2 MeV electron flux at geosynchronous
orbit is expected to fall below the high value threshold within the
next one to two days.
