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 310 publicerat klockan 2200Z på 06 NOV 1998IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z SOLAR ACTIVITY WAS MODERATE WITH A 1B/M1 FLARE FROM
REGION 8375 (N18W35) AT 1511UT. THERE WAS AN ENHANCEMENT IN THE
ENERGETIC PROTON LEVEL OF GT 10 MEV, BUT DENSITIES DID NOT PASS THE
THRESHOLD OF 10 SFU.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE TO HIGH.
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO MINOR STORM. NEAR THE START
OF THE UT DAY A SOLAR WIND STRUCTURE ASSOCIATED WITH THE PARTIAL
HALO REPORTED ON 2 NOV ARRIVED AT EARTH AND CAUSED AN INCREASE IN
ACTIVITY WITH A SINGLE PERIOD OF MINOR STORM STRENGTH. ACTIVE
CONDITIONS OCCURRED SEVERAL TIMES THROUGHOUT THE DAY. NASA GODDARD
REPORTED A FULL HALO CME WHICH OCCURRED AT 05/1945UT. THIS IS THE
FOURTH REPORTED CME IN THREE DAYS.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO ACTIVE DURING THE NEXT DAY OF THIS PERIOD.
THE REMAINING DAYS ARE EXPECTED TO BE UNSETTLED TO MAJOR STORM DUE
TO A REPORTED FULL-HALO CME ON 04/0418UT AND 05/0241.
