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.

SDF Número 119 Publicado el 2200Z a las 28 APR 2000IA. Análisis de regiones solares activas y de actividad desde 27-2100Z hasta 28-2100Z SOLAR ACTIVITY WAS LOW. ONLY TWO C-CLASS EVENTS
OCCURRED DURING THE PERIOD, THE LARGEST BEING A C5/1N WITH AN
ACCOMPANYING TYPE II RADIO SWEEP (VELOCITY - 500 KM/S) AT 28/1851UT,
FROM REGION 8967 (N19W60). THREE NEW REGION WERE NUMBERED TODAY:
8976 (S11E03), 8977 (S14W04), AND 8978 (N19E04). ALL THREE NEW
REGIONS SHOWED SIGNS OF ACTIVITY AND FAIRLY STEADY GROWTH DURING THE
DAY.
