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 146 Publicado el 2200Z a las 26 May 2011IA. Análisis de regiones solares activas y de actividad desde 25-2100Z hasta 26-2100Z Solar activity was low. A fast emerging flux region
was numbered today as Region 1223 (S15E14). This region produced
two C-class events as it evolved. The first was a C1 at 25/2103Z
then followed by a second C1 at 25/2158Z. It is configured as a Cso
group with a beta magnetic classification.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low with a chance for a C-class event.
IIA. Resumen de la actividad geofísica 25-2100Z a 26-2100Z
The geomagnetic field was mainly quiet with an active period reported
at 25/1800Z at mid-latitudes. Observations from the ACE spacecraft
indicated a possible co-rotating interaction region (CIR) at around
25/1330Z. Solar wind speed increased from around 340 to 390 km/s
and density jumped to 6 p/cc. Interplanetary magnetic field changes
included an increase in Bt to +7 nT, while Bz dipped to -6 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly unsettled with isolated active periods, and
isolated minor storms possible at high-latitudes, for the next three
days (27-29 May). Activity is expected due to a recurrent coronal
hole high speed stream. In addition, a disappearing filament
observed at 25/0801Z may possibly disturb the field on day two (28
May).
