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 192 Publicado el 2200Z a las 11 Jul 2011IA. Análisis de regiones solares activas y de actividad desde 10-2100Z hasta 11-2100Z Solar activity was low. Region 1249 (S18W04) produced a
C2/1f at 11/1103Z with a Type II radio signature (est. shock
velocity 977 km/s). A CME associated with this event became visible
in STEREO COR-2 imagery at 11/1209Z and had an estimated speed of
750 km/s. Region 1251 (N15E68) was numbered overnight and is
currently an Hsx-alpha type region. All other regions on the disk
appear to be relatively stable.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
with a slight chance for M-class activity for the next three days
(12-14 July).
IIA. Resumen de la actividad geofísica 10-2100Z a 11-2100Z
The geomagnetic field was quiet to active during the past 24 hours.
The increase in activity is due to a combination of the coronal hole
high speed stream (CH HSS) and the CME observed on 09 July. A Sudden
Impulse (SI) was observed at Earth at 11/0852Z with a 24 nT
deviation measured at the Boulder magnetometer indicating the
arrival of the CME. ACE spacecraft measurements indicated solar wind
velocities of 700 km/s towards the end of the period, most likely
due to the arrival of a second CH HSS.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be unsettled to active with isolated minor storm periods
for the next three days (12-14 July) due to the onset of a recurrent
CH HSS and the anticipated arrival (late on day two) of the CME
observed early this morning.
