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 078 Publicado el 2200Z a las 18 Mar 2012IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was low. Region 1434 (S20W40) produced
a single C1/Sn flare at 17/0237Z and ended the period as a Dso type
group with beta magnetic characteristics. Region 1435 (S25W50) grew
larger and more magnetically complex, ending as a Dao type group
with beta-gamma magnetic characteristics. A non-Earth-directed CME
was observed in SOHO/LASCO C2 imagery at 18/0024Z and believed to
originate from old Region 1429 (N19, L=295).
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for an M-class flare from Regions 1434 or 1435.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field ranged from quiet to active levels. The
coronal hole high speed stream abated over the course of the day.
Solar wind speed at the ACE spacecraft began declining from 650 km/s
at 17/2300Z to end the period near 500 km/s. Bt decreased and Bz was
neutral to slightly negative. With the departure of the high speed
stream, the geomagnetic field activity decreased from active to
quiet levels. The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels during the period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to range from quiet to active levels as a CME from 15 March
arrives early in the period on Day 1 (19 March). There is a slight
chance for minor storm levels. Activity levels are expected to
decline to unsettled on Day 2 (20 March) and quiet by Day 3 (21
March) as the effects from the CME subside.
