Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 181 publicerat klockan 2200Z på 29 JUN 2000IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 29-2100Z SOLAR ACTIVITY WAS LOW. THERE WERE SEVERAL, MOSTLY
LOW-LEVEL C-CLASS X-RAY EVENTS THIS PERIOD. THE LARGEST WAS A C6
EVENT AT 29/0751Z. THIS ACTIVITY ALONG WITH ALL THE OTHER C-CLASS
EVENTS WERE LIKELY ASSOCIATED WITH ACTIVITY ON OR BEHIND THE NW AND
SW LIMB. REGION 9062 (S16E23) IS THE MOST SIGNIFICANT REGION ON THE
VISIBLE DISK AND IS NOW A D TYPE SPOT GROUP COVERING 360 MILLIONTHS
OF WHITE LIGHT AREA. SOME GROWTH WAS NOTED IN THIS REGION DURING THE
PERIOD, BUT SIGNIFICANT ACTIVITY HAS YET TO OCCUR. A NEW ACTIVE
REGION WITH FREQUENT SURGING IS ROTATING THE NE LIMB. REMAINING
REGIONS WERE QUIET.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
THE LIKELIHOOD OF AN M-CLASS FLARE FROM THE REGIONS ON THE WEST LIMB
IS DIMINISHING QUICKLY. MOSTLY LOW LEVEL, ISOLATED C-CLASS X-RAY
EVENTS ARE EXPECTED.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 29-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE WITH THE ACTIVE CONDITIONS
CONFINED TO LOCAL NIGHTTIME HOURS.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED WITH ACTIVE CONDITIONS MOSTLY
CONFINED TO HIGH LATITUDES IN LOCAL NIGHTTIME.
