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 111 Publicado el 2200Z a las 21 Apr 2009IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity was very low. No flares were observed.
New Region 1015 (N22 W65) was numbered during the period. The
region formed on the disk and is a simple Axx alpha spot group.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field was mostly quiet. Observations from the ACE
spacecraft indicated a gradual decay in wind speeds, from near 450
km/s to 390 km/s, through about 21/1100Z. Since that time, and
through the remainder of the period, wind velocities increased to
about 460 km/s.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels for 22 April due to a
recurrent enhancement in solar wind velocities. On 23 - 24 April,
mostly quiet conditions are expected.
