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 272 Publicado el 2200Z a las 29 Sep 2011IA. Análisis de regiones solares activas y de actividad desde 28-2100Z hasta 29-2100Z Solar activity has been low for the past 24 hours.
Region 1305 (N13E16) has grown in aerial coverage and is now
considered a Cso-type spot group with a beta-gamma magnetic
configuration. The region produced a C1 event at 29/1023Z. Region
1302 (N13W16) produced a long duration C2/Sf at 29/1247Z. A Type II
Radio Sweep with an estimated speed of 608 km/s was associated with
this event. It is difficult to see in STEREO COR2 imagery but does
appear to be Earth directed with an estimated plane-of-sky speed of
628 km/s. Further analysis will be done as LASCO imagery becomes
available.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low
for the next three days (30 September - 02 October) with a chance
for isolated M-class and X-class events mainly from Region 1302.
IIA. Resumen de la actividad geofísica 28-2100Z a 29-2100Z
The geomagnetic field was mostly unsettled with isolated minor to
major storm levels observed between 29/0000-0600Z due to
substorming. Solar wind speeds jumped slightly to 600 km/s, in
conjunction with an increase in temperature and density around
29/0030Z. Bt reached +13 nT and Bz dipped south with a maximum
deviation of -10 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be quiet to unsettled with a chance for isolated active
periods early on day one (30 September) due to residual effects from
the CME. Quiet to unsettled conditions are expected on day two (01
October) due to the arrival of a recurrent coronal hole high speed
stream. Quiet to unsettled conditions are expected on day three (02
October).
