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 28 Mar 2011IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z Solar activity was at low levels. Region 1181 (S26E31)
produced a C1/Sf flare at 27/2326Z while Region 1176 (S17W11)
produced a C1 X-ray event at 28/1139Z. Region 1176 decayed in area
and spot count, but maintained a complex beta-gamma magnetic
configuration. Region 1183 (N15E54) indicated growth in area and
spot count as it continued to rotate onto the disk. At 28/1405Z, a
filament eruption was observed in STEREO-B EUVI 195 near N20, L=030.
Associated with this eruption was a CME that lifted off the NE limb,
first observed in LASCO C3 imagery at 28/1818Z. Due to the source of
this CME, it is not Earth-directed. No new regions were numbered
during the period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
all three days of the forecast period (29 - 31 March). A chance
exists all three days for isolated M-class activity.
IIA. Resumen de la actividad geofísica 27-2100Z a 28-2100Z
The geomagnetic field was quiet. ACE solar wind velocities remained
low and steady, only varying between 340 km/s to 370 km/s. The Bz
component of the IMF ranged between +/- 4 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet for day one (29 March). By days two and three
(30 - 31 March), quiet to unsettled conditions, with isolated active
periods, are expected due to the arrival of a recurrent coronal hole
high speed stream.
