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 087 Publicado el 2200Z a las 27 Mar 2012IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been at low levels. Region 1444
(N21W17) produced a C5/1f flare at 27/0308Z. Region 1442 (N12W13)
produced a C2 flare at 26/2338Z and a C1/Sf flare at 27/0430Z. SOHO
LASCO observed a full asymmetric halo CME at 26/2312Z which was
associated with Type II & Type IV radio sweeps. This CME was
determined to be a backsided event and should not be geoeffective.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a chance for an isolated M-class flare. Old Region 1429 (N19,
L=299) is expected to return to the solar disk midday on 29 March,
which should increase M-class flare probabilities. New Region 1447
(S25W55) was numbered today and is a small C-type spot group.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field was at quiet to unsettled levels. ACE data
indicate a solar sector boundary crossing during the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels for 28 March to 29
March, due to a favorably positioned negative polarity coronal hole.
Quiet levels are expected on the third day (30 March).
