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 079 Publicado el 2200Z a las 20 Mar 2011IA. Análisis de regiones solares activas y de actividad desde 19-2100Z hasta 20-2100Z Solar activity was at very low levels. Region 1175
(N14W36) continued to grow in areal coverage and produced the
largest event of the period, a B7 X-ray event at 20/0733Z. Surging
and low-level B-class X-ray emissions from the vicinity of the SE
limb signal the return of old Region 1165 (S20, L=198).
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
predominately very low levels with a chance for C-class events for
the next three days (21 - 23 March). A slight chance for isolated
M-class activity exists all three days due to the return of old
Regions 1165 late on 21 March and 1164 (N24, L=179) late on 22
March.
IIA. Resumen de la actividad geofísica 19-2100Z a 20-2100Z
The geomagnetic field was quiet. Solar wind velocities at the ACE
satellite remained low, averaging about 350 km/s. The Bz component
of the interplanetary magnetic field was southward the entire
period, not varying much beyond 0 to -5 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at predominately quiet levels for days one and two
(21 - 22 March). By midday on day three (23 March), a small coronal
hole high speed stream is expected to rotate into a geoeffective
position.
