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 144 Publicado el 2200Z a las 23 May 2012IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z Solar activity was low. Region 1484 (N11W56) produced
a C1/Sf flare at 23/0027Z. Region 1484 decayed slightly in its
leader and intermediate spots. Slight growth was observed in Region
1483 (S24W79) as it approached the west limb. New Region 1489
(S30E40) was numbered today. The rest of the spotted regions showed
no significant changes. No earth directed CMEs were observed during
the reporting period.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low to low with a slight chance for an M-class flare for the
forecast period (24 - 26 May).
IIA. Resumen de la actividad geofísica 22-2100Z a 23-2100Z
The geomagnetic field ranged from quiet to minor storming. Early on
23 May, solar wind speed at the ACE spacecraft increased from
approximately 430 km/s to 630 km/s while the interplanetary magnetic
field (IMF) fluctuated between +/- 10 nT. The geomagnetic field
responded with active to minor storm periods between 23/0000 -
0900Z. By about 23/0600Z, total field strength decreased to
approximately 4 - 5 nT while the Bz component remained mostly
positive. Solar wind speed remained fairly steady around 580 km/s
to 600 km/s through the end of the reporting period.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with a chance for further active
periods on day 1 (24 May). Mostly quiet conditions are expected on
day 2 (25 May). On day 3 (26 May), quiet to unsettled conditions
are expected with a chance for isolated active periods around
mid-day as a glancing blow from the 22 May CME is possible.
