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 054 Publicado el 2200Z a las 23 FEB 1998

IA. Análisis de regiones solares activas y de actividad desde 22-2100Z hasta 23-2100Z

SOLAR ACTIVITY WAS LOW. TWO OPTICALLY UNCORRELATED C-CLASS X-RAY BURSTS OCCURRED. A WEAK TYPE IV RADIO SWEEP WAS DETECTED AT 23/0017UT. BRIGHT LOOP STRUCTURES WERE VISIBLE ABOVE OLD REGION 8156 (NOW A DAY BEYOND THE WEST LIMB) AROUND THE TIME OF THE SWEEP, MAKING IT THE LIKELY SOURCE. REGION 8158 (S18W82) DISPLAYED GRADUAL GROWTH AND PRODUCED A COUPLE SUBFLARES AS IT APPROACHED THE WEST LIMB. NEWLY NUMBERED REGION 8164 (N18E14) EMERGED RAPIDLY EARLY IN THE PERIOD, THEN STABILIZED AS A SMALL B-TYPE. NEW REGION 8165 (N27E53) WAS ALSO NUMBERED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE LOW. REGIONS 8158 AND 8164 MAY PRODUCE C-CLASS FLARES.
IIA. Resumen de la actividad geofísica 22-2100Z a 23-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV ELECTRON FLUX REACHED HIGH LEVELS LATE IN THE PERIOD.
IIB. Pronóstico de la actividad geofísica
GEOMAGNETIC FIELD ACTIVITY IS EXPECTED TO INCREASE TO UNSETTLED LEVELS DURING THE PERIOD. THE GREATER THAN 2 MEV ELECTRON FLUX IS EXPECTED TO GRADUALLY DECLINE TO MODERATE TO NORMAL LEVELS.
