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 209 publicerat klockan 2200Z på 27 JUL 2000IA. Analys av solfläcksgrupper och solaktivitet från 26-2100Z till 27-2100Z SOLAR ACTIVITY HAS BEEN MODERATE. REGION 9090 (N14W76)
PRODUCED AN M2/SB FLARE AT 27/0410Z WITH AN ASSOCIATED TENFLARE. AN
OPTICALLY UNCORRELATED M1 FLARE OCCURRED AT 27/1711Z, LIKELY DUE TO
ACTIVITY FROM REGION 9087, BEHIND THE WEST LIMB. A FULL HALO WAS
EVIDENT IN SOHO/LASCO IMAGERY BEGINNING AT 1954Z. REGIONS 9090 AND
9097 (N09W41) BOTH APPEAR TO BE DECAYING IN SIZE AND COMPLEXITY.
NEW REGIONS 9104 (S23E65), 9105 (N13E81), AND 9106 (S10W15) WERE
NUMBERED TODAY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO PERSIST
AT MODERATE LEVELS FOR THE NEXT THREE DAYS.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 26/2100Z TO 27/2100Z:
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED, WITH ISOLATED
ACTIVE PERIODS AT HIGHER LATITUDES EARLY IN THE DAY.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BECOME ACTIVE, WITH A POSSIBILITY OF MINOR STORM PERIODS
AT HIGHER LATITUDES OVER THE NEXT TWO DAYS. THIS INCREASED ACTIVITY
IS EXPECTED IN RESPONSE TO THE CME OBSERVED ON 25 JULY. ACTIVITY
SHOULD DECREASE TO UNSETTLED LEVELS BY THE THIRD DAY.
