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 122 Publicado el 2200Z a las 02 MAY 1999IA. Análisis de regiones solares activas y de actividad desde 01-2100Z hasta 02-2100Z SOLAR ACTIVITY WAS LOW. INTERMITTENT C-CLASS ACTIVITY
OCCURRED, THE LARGEST A C7 AT 1003Z FROM REGION 8524 (N21W55).
ALTHOUGH CLOUDS HAMPERED GROUND-BASED OBSERVATIONS OF THIS EVENT, IT
WAS SEEN FROM SPACE BY SOHO. OTHER C-CLASS ACTIVITY ORIGINATED IN
REGIONS 8525 (N17E34) AND NEARBY REGION 8527 (N27E38). TWO NEW
REGIONS, 8529 (S13E10) AND 8530 (N16E53) WERE ASSIGNED.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO PERSIST
AT THE LOW LEVEL. REGIONS 8525 AND 8524 SHOULD PRODUCE C-CLASS
EVENTS THROUGHOUT THE PERIOD.
IIA. Resumen de la actividad geofísica 01-2100Z a 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE, WITH THE MOST DISTURBED
TIMES RELATED TO NIGHTTIME SUBSTORMS. THE SOLAR WIND SPEED AT ACE IS
STILL ABOVE 500 KM/S, INDICATIVE OF THE HIGH SPEED STREAM AFFECTING
THE MAGNETOSPHERE FOR THE LAST FEW DAYS. THE GREATER THAN 2 MEV
ELECTRONS AT GEOSYNCHRONOUS WERE AGAIN HIGH, PASSING THAT THRESHOLD
AT ABOUT 0900Z.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED FOR THE NEXT THREE DAYS. THE CME OF APRIL
29 MAY HAVE A SLIGHT IMPACT ON ACTIVITY EARLY IN THE FORECAST
PERIOD.
