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 101 Publicado el 2200Z a las 11 Apr 2010IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z Solar activity was very low. No flares occurred during
the past 24 hours. The solar disk was generally void of spots,
although there was some evidence late in the period for emerging
flux and possible new spot formation near S18E07.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low for the next three days (12-14 April).
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
The geomagnetic field was initially quiet but became unsettled at
mid-latitudes and active with some isolated storm periods at high
latitudes after a sudden impulse at 1305Z (5 nT in Boulder). The
sudden impulse followed observation of a weak shock at the ACE
spacecraft at 1215Z; velocity jumped from 380 km/s to about 450
km/s, and the total magnetic field increased from 4 nT to about 10
nT. The shock was followed by moderately enhanced southward field Bz
with values ranging between -3 nT to -8 nT. The shock was most
likely a result of the halo CME that was observed on 08 April. The
greater than 2 MeV electron flux at geosynchronous orbit reached
very high levels.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet with some unsettled periods for the first day
(12 April) as the current disturbance subsides. Activity is expected
to be quiet for the second and third days (13-14 April).
