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 088 Publicado el 2200Z a las 29 Mar 2011IA. Análisis de regiones solares activas y de actividad desde 28-2100Z hasta 29-2100Z Solar activity remained at low levels. Region 1183
(N15E39) produced a single C1 flare at 29/0515Z, along with several
optical subflares early in the period. Region 1183 showed gradual
spot and penumbral growth through the summary period and was
classified as an Eac group with a beta magnetic configuration.
Region 1176 (S16W24) showed no significant changes during the period
and produced an isolated B-class flare. No new regions were
numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
during the period (30 March - 01 April) with a chance for an M-class
flare from Region 1183. Old Region 1169 (N17, L=078) is expected to
return to the visible disk late on day 1 (30 March) and may also
provide a chance for an M-class flare.
IIA. Resumen de la actividad geofísica 28-2100Z a 29-2100Z
Geomagnetic activity was at quiet levels. A weak geomagnetic sudden
impulse (SI) occurred at 29/1604Z (8 nT, as measured by the Boulder
USGS magnetometer). The SI likely represented the passage of the
halo-CME observed on 24 March. ACE solar wind data showed increased
velocities (313 to 384 km/s), as well as increases in density (2 to
27 p/cc) and IMF Bt (5 to 9 nT) following the CME passage. IMF Bz
was mostly northward following the passage.
IIB. Pronóstico de la actividad geofísica
Geomagnetic activity is
expected to be at quiet to unsettled levels during the period (30
March - 01 April) with a chance for brief active levels due to
recurrent coronal hole high-speed stream effects.
