Rapporto attività solare
Ogni brillamento solare menzionato nel rapporto ha un fattore di scala, applicato dal Centro di Predizione Meteorologica Spaziale (SWPC). A causa del fattore di scala del SWPC, i brillamenti solari sono segnalati come ridotti del 42%, rispetto ai dati di qualità scientifica. Il fattore di scala è stato rimosso dai nostri dati archiviati sui brillamenti solari, per riflettere le unità fisiche reali.
Rapporto dell'Attività Geofisica Solare 1998 Aug 06 2200 UTCPreparati dal SWPC della NOAA© ed elaborati da SpaceWeatherLive.com
Rapporto Congiunto USAF/NOAA dell'Attività Solare e Geofisica
SDF Numero 218 Emesso alle 2200Z il AUG 06 1998IA. Analisi delle Regioni Solari Attive e Attività dalle 2100Z-05 alle 2100Z-06 SOLAR ACTIVITY WAS LOW. REGIONS 8293 (S22E22) AND 8296
(N17E58) PRODUCED MOST OF THE PERIOD'S FLARES, THE LARGEST BEING IN THE
LOW C-CLASS RANGE. THE DAY'S MOST SPECTACULAR ACTIVITY OCCURRED NEAR
N14 AT EAST LIMB WHERE A SPRAY WAS OBSERVED AT APPROXIMATELY 1605Z.
THIS EVENT MEASURED C-2 IN X-RAYS, AND INCLUDED TYPES II AND IV
SWEEP. ADDITIONAL SURGING WAS SEEN NEAR N26E90, MAKING PERHAPS TWO
NEW REGIONS COMING INTO VIEW. ONE NEW REGION, 8297 (N30E73) APPEARED
AS A SINGLE MATURE SPOT.
IB. Previsione dell'Attività Solare
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
HOWEVER, CONTINUED DEVELOPMENT IN REGION 8293 MAY RESULT IN AN
ISOLATED M-CLASS EVENT IN THE NEXT 3 DAYS. THIS REGION NOW SHOWS A
BETA-GAMMA DELTA MAGNETIC CONFIGURATION AND MAY PRODUCE MAJOR FLARES
IF THESE GRADIENTS STRENGTHEN. IN ADDITION, EAST LIMB MAY PROVIDE
OCCASIONAL C-CLASS EVENTS.
IIA. Sommario dell'Attività Geofisica dalle 2100Z-05 alle 2100Z-06
THE GEOMAGNETIC FIELD WAS AT QUIET TO STORM LEVELS THROUGHOUT THE
PERIOD. A TRANSIENT STRUCTURE WAS SEEN TO PASS ACE BEGINNING AT
APPROXIMATELY 0644Z. THE MASS EJECTION WAS CHARACTERIZED BY ENHANCED
SOUTHWARD BZ OF APPROXIMATELY -20 NT FOR A FEW HOURS TO FOLLOW. A
WEAK SUDDEN IMPULSE WAS OBSERVED IN THE EUROPEAN SECTOR AT 0736Z,
AND SEVERE STORM CONDITIONS FOLLOWED SHORTLY THEREAFTER. K INDICES
OF 8 AND 9 WERE REPORTED AT HIGH LATITUDES AND SLIGHTLY LESSER
VALUES WERE SEEN AT MIDDLE LATITUDES. THE MAIN DISTURBANCE WANED BY
1800Z TO QUIET CONDITIONS AT BOULDER. THIS CME MAY BE RELATED TO
SOLAR ACTIVITY WITH TYPES II AND IV SWEEP IN THE EARLY HOURS OF
AUGUST 1.
IIB. Previsione dell'Attività Geofisica
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT UNSETTLED TO MINOR STORM LEVELS FOR THE NEXT 24
HOURS AS THE CURRENT DISTURBANCE WEAKENS. EPISODES OF MINOR TO MAJOR
STORMING ARE POSSIBLE DURING LOCAL NIGHTTIME HOURS FOR THE NEXT DAY.
QUIET TO UNSETTLED CONDITIONS SHOULD END THE PERIOD.
