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 19 Mar 2011IA. Análisis de regiones solares activas y de actividad desde 18-2100Z hasta 19-2100Z Solar activity was at very low levels. Region 1175
(N14W22) grew both in areal coverage and spot count and remained a
simple bi-polar group. The remainder of the disk and limb was quiet
and stable.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
predominately very low levels with a chance for C-class activity on
day one (20 March). Days two and three (21 - 22 March) will see an
increasing chance for C-class activity, with a slight chance for
isolated M-class activity, due to the return of old Regions 1165
(S20, L=198) and 1164 (N24, L=179).
IIA. Resumen de la actividad geofísica 18-2100Z a 19-2100Z
The geomagnetic field was quiet. Solar wind velocities, as measured
at the ACE satellite, averaged 350 km/s. The Bz component of the
interplanetary field did not vary much beyond +/- 4nT through the
period. A change in magnetic field vector from a positive (away) to
a negative (toward) orientation was observed at about 19/1800Z.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominately quiet levels for the next three days
(20 - 22 March).
