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 180 publicerat klockan 2200Z på 29 Jun 2002

IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 29-2100Z

Solar activity was at low levels. Multiple low level C- and B-class flares occurred, none of which were optically correlated. Region 8 (S10W69) continues to show very gradual decay in penumbral coverage and has been stable throughout the period. Region 11 (S11W32) changed little from yesterday. Regions 18 (N15W73) and 19 (S17E72) were assigned today.
IB. Prognos för solaktivitet
Solar activity is expected to be at low levels.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 29-2100Z
The geomagnetic field activity was at quiet to unsettled levels.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field activity is expected to be at quiet to unsettled levels. Day one may see mostly unsettled conditions due to the effects of the partial-halo coronal mass ejection (CME) that occurred on 27 June.

PLAIN This message is for users of the NOAA/SEC Space Weather Operations sunspot region numbers. As you may have noticed, region number 10000 was assigned on June 14. Space Weather operations is going 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 ISES 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.
