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 053 Publicado el 2200Z a las 22 Feb 2012IA. Análisis de regiones solares activas y de actividad desde 21-2100Z hasta 22-2100Z Solar activity was very low. There were two B-class
flares during the last 24 hours. The largest of these was a B5 at
1937Z from Region 1422 (N15W38). Region 1422 has shown steady decay
during the period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low. There is a chance, however, for an isolated C-class flare.
IIA. Resumen de la actividad geofísica 21-2100Z a 22-2100Z
The geomagnetic field has been at quiet to unsettled levels. A weak
shock was observed at the ACE spacecraft at 22/0120Z and was
followed by a sudden impulse of 20 nT at 22/0223Z at the Boulder
magnetometer. Somewhat later in the day a solar sector boundary
crossing was observed (22/0815Z) and was followed by a marked
increase in solar wind velocity, indicative of the onset of a high
speed stream from a coronal hole.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with a chance for isolated active
periods during the next 24 hours as effects from the high speed
stream persist. Predominantly quiet levels are expected for the
second and third days (24-25 February).
