Activiteitenrapport
Rapport van de zonne- en geofysische activiteit van 2000 Jul 23 2200 UTCOpgemaakt door de NOAA © SWPC en verwerkt door Poollicht.be
USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 205 gepubliceerd omstreeks 2200Z op 23 JUL 2000IA. Analyse van de actieve zonneregio's en zonneactiviteit van 22-2100Z tot 23-2100Z
SOLAR ACTIVITY HAS BEEN MODERATE. REGION 9097 (N10E13)
HAS PRODUCED AN M1 EVENT AND REGION 9087 (S11W54) HAS BEEN THE
SOURCE OF SEVERAL C-CLASS EVENTS AS IT NEARS WEST LIMB. LESSER
FLARES HAVE BEEN OBSERVED IN REGIONS 9095 (N25W66), 9090 (N13W20),
AND 9085 (N14W75).
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE WITH M-CLASS EVENTS POSSIBLE FROM ANY OF SEVERAL ACTIVE
REGIONS.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 22/2100Z TO 23/2100Z:
THE GEOMAGNETIC FIELD HAS BEEN UNSETTLED TO ACTIVE. SOLAR WIND
OBSERVATIONS INDICATE NO ORGANIZED STRUCTURES NEAR EARTH ASSOCIATED
WITH THE ON-GOING PERIODS OF ACTIVITY. THE INTERPLANETARY FIELD
APPEARS TO BE LITTERED WITH IRREGULAR, MINOR FEATURES PROBABLY
ORIGINATING WITH THE CONTINUING SOLAR ACTIVITY OF THE LAST SEVERAL
DAYS. A SMALL PROTON EVENT THAT BEGAN 23/1320Z WAS DECLARED OVER AT
23/2310Z AS FLUX VALUES HAD DECLINED BELOW THE THRESHOLD FOR SUCH
EVENTS.
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN AT UNSETTLED TO ACTIVE LEVELS WITH A POSSIBILITY
OF A MINOR STORM AS REMNANTS OF VARIOUS SOLAR EVENTS CONTINUE TO BE
PRESENT OVER THE NEXT SEVERAL DAYS. THE MOST LIKELY CANDIDATE AS A
SOURCE IS A LONGER DURATION M3 EVENT THAT OCCURRED ON 22/1117Z WHOSE
IMPACT WOULD BE MOST PROBABLE ON 24 JULY. A NEGATIVE POLARITY
CORONAL HOLE IN THE NORTHERN HEMISPHERE MAY HAVE SOME IMPACT ON
GEOMAGNETIC ACTIVITY OVER THE NEXT FIVE TO SIX DAYS.
