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 359 Publicado el 2200Z a las 25 Dec 2009IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity was very low. No flares were observed.
The visible disk was spotless.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic field was quiet. Solar wind observations from the ACE
satellite decreased gradually after 24/2235Z, from 380 km/s to 282
km/s at 25/1457Z. Velocities then increased to 354 km/s at 25/1708Z
as the density increased to a peak of 13 p/cc. The interplanetary
magnetic field (IMF) increased, with the total field reaching +10 nT
at 25/1852Z. The southward component of the IMF ranged between -8 nT
and +7 nT, with the peak of -8 nT at 25/1609Z. This activity is
consistent with the arrival of the partial halo coronal mass
ejection (CME) observed on 22 December.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be predominantly quiet, with isolated unsettled periods
possible at high latitudes, on day one (26 December). Quiet levels
are expected on days two and three (27-28 December).
