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 130 Publicado el 2200Z a las 10 May 2011IA. Análisis de regiones solares activas y de actividad desde 09-2100Z hasta 10-2100Z Solar activity remained low. A C5 x-ray flare occurred
at 09/2059Z from a region rounding the northeast limb at the time of
this report. This region appeared to be the return of old Region
1193 (N17, L=266), which produced C-class flares during its previous
rotation. The C5 flare was associated with a partial-halo coronal
mass ejection (CME). The CME had an estimated plane-of-sky velocity
of 1225 km/s, based on SOHO/LASCO images, and appeared to have an
Earthward component. No new regions were numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
through the period (11 - 13 May) with a chance for an M-class flare
from the region now crossing the northeast limb.
IIA. Resumen de la actividad geofísica 09-2100Z a 10-2100Z
Geomagnetic field activity was at quiet to active levels. ACE solar
wind measurements indicated a co-rotating interaction region (CIR),
in advance of a coronal hole high-speed stream, commenced around
10/0400Z. Solar wind speeds gradually increased from 302 to 398 km/s
during the period. Interplanetary magnetic field (IMF) changes
associated with the CIR included increased Bt (peak 10 nT at
05/1338Z) and intermittent periods of southward Bz (maximum
deflection -10 nT at 05/1338Z). The greater than 2 MeV electron flux
at geosynchronous orbit briefly reached high levels during the period.
IIB. Pronóstico de la actividad geofísica
Geomagnetic activity is
expected to be at quiet to active levels on day 1 (11 May), then
increase to unsettled to active levels with a chance for minor storm
levels on day 2 (12 May) as the CH HSS persists. The CME observed
today may also disturb the field on 12 May. Activity is expected to
decrease to quiet to unsettled levels on day 3 (13 May) as the CH
HSS subsides.
