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 027 Publicado el 2200Z a las 27 JAN 1998IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z SOLAR ACTIVITY WAS LOW. REGION 8142 (S21W65) PRODUCED
THE DAY'S ONLY C-CLASS FLARE, A C5/SN AT 26/2235UT. A TYPE II RADIO
SWEEP ACCOMPANIED THE FLARE (EST. SHOCK VEL. 700 - 900 KM/SEC).
ISOLATED B-CLASS SUBFLARES OCCURRED DURING THE REMAINDER OF THE
PERIOD. REGION 8143 (S35E10) APPEARED TO STABILIZE WHILE MAINTAINING
A MODERATELY COMPLEX MAGNETIC STRUCTURE. NO NEW REGIONS WERE
ASSIGNED.
IB. Pronóstico de la actividad solar
SOLAR ACTIV ITY IS EXPECTED TO REMAIN
LOW. REGIONS 8142 AND 8143 COULD PRODUCE ISOLATED C-CLASS FLARES.
THERE IS ALSO A SLIGHT CHANCE FOR AN M-CLASS FLARE FROM EITHER
REGION.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE UNSETTLED PERIODS
WERE LIMITED TO HIGH LATITUDES.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY QUIET THROUGH 28 JANUARY. A DISTURBANCE IS
EXPECTED DURING 29 - 30 JANUARY IN RESPONSE TO THE PARTIAL-HALO CME
THAT OCCURRED ON 25 JANUARY. UNSETTLED TO MINOR STORM LEVELS ARE
EXPECTED DURING THE DISTURBANCE.
