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 007 Publicado el 2200Z a las 07 Jan 2011IA. Análisis de regiones solares activas y de actividad desde 06-2100Z hasta 07-2100Z Solar activity was at very low levels. Departing Region
1141 (N33, L=263) produced a B5 X-ray event at 07/1520Z as the
region rotated around the west limb. New Region 1143 (S22E16)
emerged on the disk as a D-type bi-polar group and exhibited steady
growth through the period. Region 1139 (S27W74) redeveloped spots
after a 6-day spotless plage interval. Region 1140 (N33W24)
redeveloped spots to the north of the large H spot and was
reclassified as a C-type bi-polar group. Region 1142 (S14W45)
decayed to a uni-polar group.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
at predominately very low levels during the forecast period (08 - 10
January). A chance for isolated C-class activity exists all three
days.
IIA. Resumen de la actividad geofísica 06-2100Z a 07-2100Z
Geomagnetic field activity ranged from quiet to active levels with a
minor storm interval observed between 06/2100 - 2400Z. The increase
in activity was due to the onset of a coronal hole high speed
stream. Solar wind velocities, as observed at the ACE satellite,
steadily increased throughout the period from about 450 km/s at
06/2100Z to a maximum of 627 km/s at 07/1545Z. Velocities remained
near 600 km/s through the end of the period. The Bz component of the
interplanetary magnetic field reached a maximum southward value of
-14nT at 06/2226Z and remained southward between -5 nT to -10 nT for
about 6 hours. For the remainder of the period, Bz fluctuated
between +/- 4 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominately quiet to unsettled levels all three
days of the forecast period (08 - 10 January). Isolated active to
minor storm periods are possible on 08 and 09 January. This activity
is due to continued effects of the coronal hole high speed stream.
