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 018 Publicado el 2200Z a las 18 JAN 1999IA. Análisis de regiones solares activas y de actividad desde 17-2100Z hasta 18-2100Z SOLAR ACTIVITY WAS MODERATE. THIS WAS DUE TO A SINGLE
M-CLASS EVENT, AN M2/1N FLARE AT 18/0804UT, FROM REGION 8440
(S18E64). REGIONS 8439 (S24E00) AND 8440 WERE THE MOST ACTIVE
REGIONS, BOTH PRODUCING NUMEROUS C-CLASS EVENTS. REGION 8442
(N25W28) HAS BEGUN TO SHOW SOME ACTIVITY THIS PERIOD, PRODUCING A
C1/SF AT 18/1839UT. REGION 8442 HAS ALSO SHOWN AN INCREASE IN THE
NUMBER OF SPOTS FROM 8 TO 15 AND A CHANGE IN MAGNETIC CLASSIFICATION
FROM A SIMPLE BETA TO A BETA-GAMMA-DELTA. A NEW REGION WAS NUMBERED
TODAY; 8443 (S18E64). CURRENTLY A 3 SPOT BXO BETA SPOT GROUP.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGIONS 8439 AND 8440 ARE STILL CAPABLE OF PRODUCING
M-CLASS EVENTS.
IIA. Resumen de la actividad geofísica 17-2100Z a 18-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS A HIGH LEVELS FOR THE DAY
UNTIL AROUND 18/1900UT WHEN IT DROPPED WELL BELOW THRESHOLD LEVELS.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
