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 233 Publicado el 2200Z a las 20 Aug 2012IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was very low. Region 1543 (N21, L=021)
produced the largest event of the period, a B8 flare at 19/2315Z,
off of the northwest limb. Region 1548 (N20E47) also produced a low
level B-class flare. The remaining spotted regions were stable and
quiet. A full halo CME was observed in SOHO/LASCO C3 coronagraph
imagery beginning at 19/1918Z with an estimated plane-of-sky speed
of 605 km/s. STEREO-A and STEREO-B COR2 imagery shows this CME to be
a back-sided event and is not expected to be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low with a slight chance for an M-class event for the next
three days (21-23 August).
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was quiet to unsettled with an isolated active
period between 19/2100Z to 20/0000Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with a slight chance for active
conditions on days 1-2 (21-22 August) due to continued effects from
the coronal hole high speed stream. On day 3 (23 August) conditions
are expected to return to predominately quiet levels.
