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 233 Publicado el 2200Z a las 21 Aug 2003IA. Análisis de regiones solares activas y de actividad desde 20-2100Z hasta 21-2100Z Solar activity was low. A number of small x-ray flares
occurred in Region 431 (S10W90) from its location just beyond the
west limb. The largest was a C4 at 21/1522 UTC. The largest region
presently on the disk is 436 (N07E17) but it appears relatively
simple and has not flared today. New Regions 438 (S31W31), 439
(N08W23), 440 (S08E12), and 441 (N12E48) emerged on the disk.
IB. Pronóstico de la actividad solar
Solar activity is expected to be low.
C-class flares are possible in Regions 431, 436, and an area not
yet numbered rotating around the east limb near S12E90.
IIA. Resumen de la actividad geofísica 20-2100Z a 21-2100Z
The geomagnetic field ranged from unsettled to severe storm levels.
The most disturbed period was from 21/0600 to 0900 UTC. ACE solar
wind data indicates the gradual onset of a coronal hole
high-speed-stream over the past 24 hours. Current solar wind
parameters include speed at about 700 km/s, density from 1 to 5
p/cc, and Bz fluctuating between +/- 10 nT.
IIB. Pronóstico de la actividad geofísica
The geomagnetic field is
expected to be at mostly active to minor storm levels for the
duration of the forecast period as the high-speed-stream disturbance
continues.
