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 261 Publicado el 2200Z a las 18 SEP 1999IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY WAS LOW. REGION 8700 (N13E07) PRODUCED
THE LARGEST FLARE SINCE YESTERDAY, A C8/2F AT 17/2212UT. SEVERAL
SUBFLARES AND FLARE-BRIGHT PLAGE FLUCTUATIONS ALSO OCCURRED IN THIS
REGION. 8700 SUNSPOTS CONTINUE TO EXHIBIT MIXED POLARITIES. REGION
8699 (N22W65) ALSO PRODUCED C-CLASS ACTIVITY, THE LARGEST BEING A
C2/SF AT 18/1821UT. NEW REGION 8705 (S11E28) EMERGED ON THE DISK.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. C-CLASS ACTIVITY IS EXPECTED IN REGIONS 8699 AND 8700.
AN ISOLATED M-CLASS FLARE IS POSSIBLE IN REGION 8700.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO ACTIVE. ACTIVITY LEVELS
CONTINUED TO FLUCTUATE IN RESPONSE TO SIMILAR SOLAR WIND (HIGH SPEED
AND VARIABLE BZ) EXPERIENCED FOR THE PAST FEW DAYS. THE GREATER THAN
2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS HIGH.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET TO UNSETTLED FOR THE NEXT SEVERAL HOURS.
ACTIVE TO STORM CONDITIONS ARE POSSIBLE LATE ON THE 19TH, CONTINUING
THROUGH THE 20TH, DUE TO THE CME/DSF DETECTED ON THE 16TH. THE
GREATER THAN 2 MEV ELECTRON FLUX SHOULD REMAIN MODERATE TO HIGH.
