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 239 Publicado el 2200Z a las 27 Aug 2011IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z Solar activity has been at very low levels for the past
24 hours. There are currently 9 numbered regions on the visible
disk, but only 5 regions have retained their spots. All spotted
regions seem to be either stable or in a decay phase. The largest
flare of the period was a B8 x-ray event, observed at 0446Z, from
Region 1275 (N07W08). A CME was observed in LASCO C2 and STEREO
Behind COR2 imagery. Analysis indicates that the CME is a backsided
event.
IB. Pronóstico de la actividad solar
Solar activity is expected to be at
very low levels with a chance for C-class events for the next three
days (28-30 August). Even though Region 1271 (N16W82) is expected to
rotate off the visible disk in the next 24 hours, it appears old
Region 1267 (S18, L=246) is rotating onto the east limb.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at quiet to unsettled levels with a chance for active
periods at high latitudes for the next two days (28-29 August), as a
coronal hole high speed stream (CH HSS) moves into a geoeffective
position. Predominantly quiet levels are expected on day three (30
August), as the effects of the CH HSS wane.
