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 206 Publicado el 2200Z a las 24 Jul 2012IA. Análisis de regiones solares activas y de actividad desde 23-2100Z hasta 24-2100Z Solar activity was low. New Region 1530 (S19E68) was
responsible for multiple low level C-class flares. The largest was
a C4/Sf at 24/1905Z. SDO and STEREO-B EUVI 195 imagery show
brightening behind the northeast and southeast limbs, suggesting the
presence of more active regions yet to rotate onto the visible disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
low levels.
IIA. Resumen de la actividad geofísica 23-2100Z a 24-2100Z
The geomagnetic field was at quiet to unsettled levels with an
isolated minor storm period at high latitudes from 24/1200 - 1500Z.
Solar wind measurements at the ACE spacecraft showed an increase in
solar wind speed from approximately 450 km/s to 580 km/s by 24/0830Z
before decreasing to 500 km/s by the end of the period. This is
likely due to the influence of a geoeffective coronal hole high
speed stream. The greater than 10 MeV proton event at
geosynchronous orbit that began at 23/1545Z, reached a maximum flux
of 12 pfu at 23/2145Z and continued to fluctuate near the 10 pfu
threshold. 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 slight chance for
active periods on day 1 (25 July) due to persistent effects from the
coronal hole high speed stream. Mostly quiet conditions are
expected for days 2 - 3 (26 - 27 July).
