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 165 publicerat klockan 2200Z på 14 Jun 2002

IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z

Solar activity was at low levels. Three new regions were numbered today: Region 9999 (S05W61), Region 0000 (N18E50), and Region 1 (N20E70). Please refer to the attached plain message for a region numbering discussion. Region 9987 (S16W86) produced a C1 flare at 14/1020 UTC. Region 9991(S21W21) has remained relatively stable. New Region 1 has shown some surging but due its limb proximity prevents a complete analysis.
IB. Prognos för solaktivitet
Solar activity is expected to be low. Region 9987 and 9991 have the potential of C- and low level M-class events. Old Region 9963 (N17, L= 318) is due to return on day two of the forecast period.
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
The geomagnetic field was at quiet levels.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to be a quiet to unsettled levels. Isolated active conditions are possible on day one of the forecast period due to coronal hole effects.

PlAIN: This message is for users of the NOAA/SEC Space Weather Operations sunspot region numbers. As you may have noticed, we are steadily approaching region number 10000. The plan for Space Weather operations is to go through the sequence of Region numbers as 9998, 9999, 0000, 0001, and so on. SEC's product text discussions of the active regions will ignore the leading zeroes (for example, we will say 'Region number 5' rather than Region number '0005'). However, the Geoalert product, the Region Report product, as well as the USAF and IUWDS data exchange codes will preserve the 4 digit format. The necessity of using four digits is for operational purposes only. For historical purposes all regions beyond Region 9999 will be understood to be in a series of region numbers 10000 and higher.
