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 2000IA. Análisis de regiones solares activas y de actividad desde 26-2100Z hasta 27-2100Z SOLAR ACTIVITY HAS BEEN VERY LOW. REGION 8844 (N05W60)
IS THE LARGEST GROUP ON THE DISK BUT WAS QUIET AND APPEARED TO BE IN
DECLINE. NEW REGION 8848 (S09E66) ROTATED INTO VIEW TODAY AS A
SMALL, C-TYPE GROUP, AND NEW REGION 8846 (N37E39) EMERGED AS A
SMALL, HIGH LATITUDE A-TYPE SUNSPOT GROUP.
IB. Pronóstico de la actividad solar
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW.
IIA. Resumen de la actividad geofísica 26-2100Z a 27-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET UNTIL A SUDDEN IMPULSE WAS
OBSERVED AT 1455 UT. SINCE THEN CONDITIONS HAVE BEEN UNSETTLED TO
ACTIVE. A SHOCK WAS SEEN AT ACE AT 1350Z AND WAS FOLLOWED BY A HIGH
DENSITY FLOW WITH STRONGLY FLUCTUATING MAGNETIC FIELDS. SIMULTANEOUS
WITH THE SHOCK WAS A REVERSAL OF THE SPIRAL ANGLE (PHI) FROM TOWARDS
TO AWAY. AFTER 1830Z THE SOLAR WIND SPEED AND TEMPERATURE BEGAN TO
RISE CONSIDERABLY AS DENSITY BEGAN TO FALL. THESE SIGNATURES ARE
CONSISTENT WITH A STRONG, CO-ROTATING INTERACTION REGION WHICH MOST
LIKELY WILL BE FOLLOWED BY A HIGH SPEED CORONAL HOLE WIND STREAM.
IIB. Pronóstico de la actividad geofísica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY ACTIVE FOR THE NEXT TWO DAYS, WITH PERIODS OF
MINOR STORM LEVELS DURING THE FIRST PART OF DAY ONE. CONDITIONS WILL
DECLINE TO UNSETTLED LEVELS WITH OCCASIONAL ACTIVE PERIODS BY THE
THIRD DAY.
