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 199 publicerat klockan 2200Z på 17 JUL 2000IA. Analys av solfläcksgrupper och solaktivitet från 16-2100Z till 17-2100Z SOLAR ACTIVITY WAS MODERATE. SEVERAL REGIONS PRODUCED
SMALL M-CLASS FLARES. REGION 9090 (N12E59) PRODUCED AN M1/1N EVENT
AT 16/2147Z; REGION 9077 (N18W46) PRODUCED AN M1/2F AT 17/0004Z; AND
REGION 9087 (S12 E31) GENERATED AN M1/1F AT 17/1344Z AND AN M2/1N AT
17/2027Z WITH A 280 SFU BURST AT 2695 MHZ AND A TYPE II. REGION
9077 SLOWLY DECLINED DURING THE PERIOD. REGION 9087 EXHIBITED
GROWTH. THE OTHER SIGNIFICANT REGIONS ON THE DISK WERE
PREDOMINANTLY STABLE. A LARGE MASS EJECTION WAS OBSERVED OVER THE
EAST LIMB AROUND 17/1100Z.
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD BE MODERATE TO
HIGH. THE THREE REGIONS MENTIONED ABOVE ARE OBVIOUSLY CAPABLE OF
OCCASIONAL M-CLASS EVENTS. CONTINUED GROWTH IN REGION 9087 WOULD
INCREASE THE FREQUENCY OF M-CLASS EVENTS FROM THAT LOCATION. THERE
REMAINS A POSSIBILITY OF A MAJOR FLARE FROM REGIONS 9077, 9087, AND
9090.
IIA. Sammanfattning av geofysisk aktivitet 16-2100Z till 17-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. SOLAR WIND VELOCITY
DECLINED DURING THE PERIOD FROM APPROXIMATELY 750 TO 600 KM/S. THE
GREATER THAN 10 MEV PROTON FLUX BEGAN THE PERIOD AT APPROXIMATELY
180 PFU AND BY ISSUE TIME WERE NEAR 50 PFU. THE POLAR CAP
ABSORPTION EVENT ENDED AT 17/1943Z. THE FORBUSH DECREASE REMAINED
IN PROGRESS.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD BE
PREDOMINANTLY QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. ISOLATED
ACTIVE PERIODS ARE POSSIBLE AS LONG AS SOLAR WIND VELOCITY REMAINS
ELEVATED. THE SOLAR PROTON EVENT SHOULD CONTINUE TO DECAY SLOWLY
AND BE BELOW EVENT THRESHOLD AROUND 19 JULY. HOWEVER, IT REMAINS
POSSIBLE THAT REGION 9077 COULD PRODUCE ANOTHER MAJOR EVENT THAT
COULD RESULT IN AN ADDITIONAL INJECTION OF ENERGETIC PROTONS.
