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 167 publicerat klockan 2200Z på 16 Jun 2002

IA. Analys av solfläcksgrupper och solaktivitet från 15-2100Z till 16-2100Z

Solar activity was low. The most notable event of the period was a long duration C1.0 flare at 16/0814 UTC. There were no optical reports associated with this event, but a CME was evident in LASCO imagery just following the flare, from a presumed source behind the northeast limb, near N35. Active prominences have been visible in H-alpha imagery in this area for the past 24 hours. Other activity included an optically uncorrelated C1.4 flare at 16/0332 UTC. B-class activity was observed in Region 9991 (S21W47) and Region 3 (N00E49). New Region 5 (N13E74) rotated into view and was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to remain mostly low for the next three days.
IIA. Sammanfattning av geofysisk aktivitet 15-2100Z till 16-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to persist at quiet to unsettled levels for the next three days.

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 regions numbers 10000 and higher.
