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 060 Publicado el 2200Z a las 29 Feb 2004IA. Análisis de regiones solares activas y de actividad desde 28-2100Z hasta 29-2100Z Solar activity was very low. Only one flare occurred
during the past 24 hours, a B4 at 0617 UTC from Region 564 (N13W67).
This Region continues to dominate the disk in size and complexity,
but appears to be in slow decline as it approaches west limb. A CME
was observed on the southwest limb by LASCO, beginning at 1230 UTC.
The plane-of-sky speed was estimated to be about 500 km/s. EIT 195
difference images show that the CME must have originated from behind
the solar disk since the associated activity is first seen off the
southwest limb starting at 1200 UTC. The CME is not earthward
directed.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
There continues to be a chance, however, for an isolated M-class
event from Region 564.
IIA. Resumen de la actividad geofísica 28-2100Z a 29-2100Z
The geomagnetic field ranged from quiet to minor storm levels during
the past 24 hours. Although unsettled to active levels predominated,
there was an interval of mostly minor storm level activity between
0900-1500 UTC. Solar wind data show that the activity is being
driven by a high speed stream which is associated with a favorably
positioned coronal hole.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be mostly active, with possible minor storm periods, for
tomorrow (1 March). Unsettled to active conditions are expected for
the 2nd day (2 March), and mostly unsettled should prevail by 3
March.
