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 049 Publicado el 2200Z a las 18 Feb 2011IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z Solar activity was high during the past 24 hours.
Region 1158 (S19W64) produced several C-class events with a C1 at
17/2135Z that was associated with a Type II Sweep and an M1 event at
18/1303Z. Region 1161 (N12W02) grew slightly in area and maintained
a beta-gamma magnetic classification. New Region 1162 (N18W06) was
numbered today and developed rapidly into a Dai-type sunspot group
with a beta-gamma magnetic classification. The bulk of the activity
originated from this new region, including two M1 events and an M6
event at 18/1011Z.
IB. Pronóstico de la actividad solar
Solar activity is expected to be
moderate with a chance for isolated high level activity for the next
three days (19-21 February).
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
The geomagnetic field was unsettled to active with an isolated minor
storm period at high latitudes. This activity was due to the
effects of the CMEs associated with two M-class events and an
X-class event observed from 13-15 February. A sudden impulse of 33
nT was observed at 18/0136Z at the Boulder magnetometer in
association with this event. The ACE spacecraft indicated solar wind
velocities increased to approximately 700 km/s along with a
sustained period of southward Bz between -10 and -15 nT from
18/0200-0300Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with a chance for isolated active
periods for day one (19 February) due to the residual effects of the
recent CMEs. Days two and three (20-21 February) are expected to be
mostly quiet.
