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 170 publicerat klockan 2200Z på 18 JUN 2000IA. Analys av solfläcksgrupper och solaktivitet från 17-2100Z till 18-2100Z SOLAR ACTIVITY WAS HIGH. REGION 9033 (S25W85) PRODUCED
AN X1/SF FLARE AT 18/0159Z WITH AN ASSOCIATED 300 SFU TENFLARE, A
245 MHZ RADIO BURST OF 11000 SFU, AND A TYPE II RADIO SWEEP WITH A
SPEED OF 660 KM/S. A BRIGHT SURGE ON THE LIMB WAS ALSO OBSERVED WITH
THIS EVENT REACHING A RADIAL EXTENT OF .21 RV, AND THE SOHO/LASCO
IMAGERY INDICATED AN ASSOCIATED CME. A 30 DEGREE FILAMENT AT N55E62
DISAPPEARED BETWEEN 17/1928Z AND 18/1158Z. A NEW REGION WAS NUMBERED
TODAY AS REGION 9052 (S29W10).
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. THE POSSIBILITY OF AN ISOLATED X-CLASS FLARE REMAINS.
IIA. Sammanfattning av geofysisk aktivitet 17-2100Z till 18-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. GOES GT 10 MEV PROTON
FLUXES BECAME SLIGHTLY ENHANCED DURING THE EVENT MENTIONED IN PART
IA, BUT REMAINED BELOW EVENT THRESHOLD AND RETURNED TO BACKGROUND
LEVELS.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED. ISOLATED PERIODS OF ACTIVE
CONDITIONS ARE POSSIBLE FOR THE FORECAST PERIOD AS A RESULT OF THE
CME ACTIVITY OVER THE PAST THREE DAYS.
