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 120 Publicado el 2200Z a las 29 Apr 2012IA. Análisis de regiones solares activas y de actividad desde 28-2100Z hasta 29-2100Z Solar activity was at low levels due to low-level
C-class events from Regions 1465 (S18W80), 1466 (N13W65), 1467
(N12E04), 1469 (S19W01) and 1471 (S23E57). New Region 1472 (S29E40)
emerged on the disk as a simple bi-polar group. GONG H-alpha and
SDO/AIA 304 imagery observed a filament eruption along a six degree
long channel centered near N06E36, just to the SE of Region 1467.
This eruption occurred during the period 28/1800 - 2000Z. Associated
multiple CME activity was visible off the east limb as observed in
LASCO/C2 imagery at 28/1936Z and 28/2024Z. At the time of this
report, analysis was ongoing as to the geoeffective nature of these
CMEs.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
for the next three days (30 April - 02 May).
IIA. Resumen de la actividad geofísica 28-2100Z a 29-2100Z
The geomagnetic field was at quiet to unsettled levels. Through the
period, ACE solar wind velocities ranged between 380 to 440 km/s
while the Bz component of the interplanetary magnetic field did not
vary much beyond +/- 4 nT. 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 be at predominately quiet levels for day one (30 April).
By days two and three (01 - 02 May), quiet to unsettled levels with
a slight chance for isolated active periods are expected as a
coronal hole high speed stream moves into a geoeffective position.
