Отчет о солнечной активности
Любая солнечная вспышка, упомянутая в этом расчете, имеет масштабирующий коэффициент, применяемый Центром прогнозирования космической погоды (SWPC). Из-за него солнечные вспышки здесь на 42% слабее, чем в научных данных. Из наших архивов этот коэффициент был удален, чтобы показать реальные величины вспышек.
Отчет о солнечно-геофизической активности 2000 Oct 01 2200 UTC
Подготовлено NOAA © SWPC и представлено SpaceWeatherLive.comСовместный отчет USAF/NOAA о солнечной и геофизической активности
Количество SD 275 на уровне 2200Z 01 OCT 2000
IA. Анализ активных солнечных регионов и активности от 30 - 2100Z до 01 - 2100Z
SOLAR ACTIVITY WAS HIGH. TWO OPTICALLY UNCORRELATED
X-RAY FLARES, AN X1 AT 30/2321Z AND M5 AT 01/0701Z, ARE BELIEVED TO
HAVE BEEN PRODUCED BY REGION 9169 THAT JUST RECENTLY PASSED BEHIND
THE WEST LIMB. A 200 SFU TENFLARE ACCOMPANIED THE M5 EVENT. A
LONG-DURATION M2 FLARE AT 01/1410Z IS BELIEVED TO HAVE ORIGINATED
FROM REGION 9178 (S22E24); THIS REGION ALSO PRODUCED NUMEROUS
C-CLASS FLARES. REGION 9176 (S10E15) PRODUCED A C3/SF FLARE WITH AN
ASSOCIATED TYPE II RADIO SWEEP (SHOCK SPEED 1100 KM/S). A 12-DEGREE
FILAMENT DISAPPEARED OVERNIGHT FROM N22W37. NEW REGION 9180
(S34W21) WAS NUMBERED TODAY.
IB. Прогноз солнечной активности
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. WHILE REGION 9169, WHICH IS BELIEVED TO HAVE CAUSED
THE RECENT MAJOR FLARES, IS NOW WELL BEHIND THE LIMB, BOTH REGIONS
9176 (S09E18) AND 9178 REMAIN CAPABLE OF PRODUCING M-FLARES.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 30/2100Z TO 01/2100Z:
THE GEOMAGNETIC FIELD RANGED FROM ACTIVE TO QUIET CONDITIONS. ACTIVE
CONDITIONS WERE OBSERVED UNTIL APPROXIMATELY 01/06Z, AT WHICH POINT
THE SOLAR WIND SPEED AND INTERPLANETARY MAGNETIC FIELD BEGAN TO DROP
TO NOMINAL LEVELS. RELATIVISTIC ELECTRONS AT GEO-SYNCHRONOUS ORBIT
REACHED MODERATE LEVELS.
IIB. Прогноз геофизической активности
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE FIRST DAY, WITH ACTIVITY
INCREASING FOR THE SECOND AND THIRD DAYS. A RECURRENT CORONAL HOLE
WILL BE GEO-EFFECTIVELY POSITIONED BY DAY TWO. IN ADDITION, EFFECTS
FROM ANY OF THE MANY SOLAR EVENTS TODAY COULD IMPACT THE EARTH LATE
ON DAY TWO INTO DAY THREE.
