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 058 Publicado el 2200Z a las 27 Feb 2009IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity was very low. Unspotted Region 1013
(N26W19) produced an A3 x-ray event at 27/0714Z with a subsequent
slow moving, asymmetric CME first observed in LASCO C2 imagery
lifting off the NW limb at 27/0906Z. A 9 degree filament located at
S38W46 was observed to have lifted off the disk between 26/2358Z to
27/1423Z.
IB. Pronóstico de la actividad solar
Solar activity is expected to remain
very low.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field was predominately quiet to unsettled with an
isolated active period observed at middle latitudes at 27/1200Z.
This activity was most likely produced by a low-latitude extension
of the southern polar coronal hole. During the summary period,
solar winds speed gradually increased from about 400 km/s to near
650 km/s by 27/1200Z and maintained that velocity through the end of
the period. During the elevated portion of the high speed flow, the
Bz component of the IMF did not vary much beyond +/- 5 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be predominately quiet for the next three days (28
February - 02 March). The CME mentioned earlier is not expected to
be geoeffective.
