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 070 Publicado el 2200Z a las 11 Mar 2010IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z Solar activity was very low. Todays activity consisted
of a few, low-level B-class events. The largest of these was a B4/Sf
at 2039Z from Region 1054 (N15E43). This region showed steady growth
throughout the day and is classified as a D type group. The total
sunspot area increased to about 160 millionths near the end of the
period. New Region 1055 (S23W15) also continued to emerge slowly and
is currently a C-type group with about 30 millionths in area.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low. There is a chance for an isolated C-class flare from
Region 1054 or 1055.
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
The geomagnetic field was quiet to unsettled at mid latitudes and was
mostly unsettled to active at high latitudes. However, there were
some isolated storm intervals at high latitudes between 0000-1200Z.
Solar wind observations from ACE showed elevated velocities around
460-500 km/s with low density (1-3 p/cc). The signatures are
consistent with a weak high speed stream, presumably from the
southward extension of the northern polar coronal hole.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet for the next two days (12-13 March). An
increase to quiet to unsettled is possible on the third day (14
March) due to effects from a recurrent solar sector boundary.
