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 138 Publicado el 2200Z a las 17 MAY 2000IA. Análisis de regiones solares activas y de actividad desde 16-2100Z hasta 17-2100Z SOLAR ACTIVITY WAS LOW. THE MOST ACTIVE REGIONS WERE
8996 (S21E03), 8998 (N20E17), AND 9002 (N18E48), ALL OF WHICH
PRODUCED ISOLATED C-CLASS X-RAY EVENTS AND OPTICAL SUBFLARES.
REGIONS 8996 AND 9002 CONTINUE TO BE THE LARGEST REGIONS ON THE
DISK, WITH AREAS OF 1280 AND 820 MILLIONTHS, AND SPOT COUNTS OF 53
AND 29 RESPECTIVELY. A 29 DEGREE LONG, DISAPPEARING SOLAR FILAMENT
(DSF) OCCURRED DURING THE PERIOD 17/1808-1843UT, NEAR S22W37. FOUR
NEW REGIONS WERE NUMBERED DURING THE PERIOD: 9005 (S18W56), 9006
(N26W88), 9007 (S42E12), AND 9008 (S13E50).
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE. REGIONS 8996, 8998, AND 9002 ARE ALL CAPABLE OF PRODUCING
M-CLASS EVENTS.
IIA. Resumen de la actividad geofísica 16-2100Z a 17-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE WITH MINOR STORMING
OCCURRING DURING THE PERIOD 17/03-0900UT AT MID-LATITUDES AND
17/00-0900UT AT HIGHER LATITUDES.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED IS EXPECTED TO BE UNSETTLED TO ACTIVE WITH POSSIBLE MINOR
STORMING AT HIGH LATITUDES FOR THE FIRST DAY OF THE PERIOD. THIS
INCREASED ACTIVITY WOULD BE THE RESULT OF INTERACTION WITH A CME
REPORTED ON 15 MAY. CONDITIONS SHOULD BE UNSETTLED TO ACTIVE ON THE
SECOND DAY AND QUIET TO UNSETTLED ON THE THIRD.
