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 025 Publicado el 2200Z a las 25 Jan 2012IA. Análisis de regiones solares activas y de actividad desde 24-2100Z hasta 25-2100Z Solar activity was at very low levels. As Regions 1401
(N16W66) and 1402 (N26W60) approached the west limb, they exhibited
little change over the past 24 hours, as did the remainder of the
disk and limb.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low during the period (26 - 28 January). A chance for
M-class activity exists on 26 - 27 January from Regions 1401 and
1402 before they rotate around the west limb.
IIA. Resumen de la actividad geofísica 24-2100Z a 25-2100Z
The geomagnetic field ranged from quiet to minor storm levels with
isolated high latitude major to severe storm intervals. During the
period, ACE solar wind velocities varied between a high of 625 km/s
at the beginning, and steadily decreased to a low of near 500 km/s
by the end. The Bz component of the interplanetary magnetic field
varied between +/- 10 nT through about 25/1000Z and remained weakly
south at -1 to -5 nT through the end of the period. The greater
than 10 MeV proton flux event was still in progress at the time of
this report. Proton flux levels steadily decayed to end the period
near 100 pfu.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at mostly quiet levels on day one (26 January). By
day two (27 January) and through day three (28 January), field
activity is expected to increase to quiet to unsettled levels with
isolated active periods. This increase in activity is due to a
recurrent coronal hole high speed stream expected to move into a
geoeffective position. The greater than 10 MeV proton flux event is
expected to remain above event levels through 26 January, falling to
background levels by 27 January.
