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 203 Publicado el 2200Z a las 21 Jul 2012IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity has been at very low levels for the past
24 hours. The four numbered sunspot regions remained stable and
quiet.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low levels for the next three days (22-24 July).
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field has been at quiet to unsettled levels for the
past 24 hours. Solar wind speeds, as measured by the ACE spacecraft,
indicated speeds above nominal levels ranging from 400-520 km/s. The
greater than 10 MeV proton event observed at geosynchronous orbit
that began at 17/1715Z ended early in the period at 21/0310Z. Peak
flux levels observed with this event were 136 pfu at 18/0600Z. 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 quiet to unsettled levels with a chance for active
periods for the next three days (22-24 July) as a coronal hole high
speed stream becomes geoeffective.
