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 317 publicerat klockan 2200Z på 12 Nov 2000

IA. Analys av solfläcksgrupper och solaktivitet från 11-2100Z till 12-2100Z

Solar activity has been low during the past 24 hours. Region 9227 (S11W02) produced today's largest event, a C4/1f flare at 1426Z. This group continues to show slow growth and is currently the largest group on the disk at 180 millionths. The other active regions on the disk were stable and quiet.
IB. Prognos för solaktivitet
Solar activity is expected to be mostly low, but there is a slight chance for an isolated M-class event.
IIA. Sammanfattning av geofysisk aktivitet 11-2100Z till 12-2100Z
The geomagnetic field was at quiet to minor storm levels. Unsettled to active levels prevailed for most of the period, but there was a 3 hour minor storm interval from 0300-0600Z. Solar wind observations indicate the presence of a high speed stream associated with a favorably positioned, transequatorial coronal hole. The greater than 10 MeV proton event continued to show flux levels above threshold throughout the period with a very slow decline. The current greater than 10 MeV flux at 12/2100Z observed by GOES-8 was 12.4 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to be unsettled to active for the next 24 hours. A decline to mostly unsettled is expected during the second and third days. The greater than 10 MeV proton event is expected to end before the end of 12 November (UTC time).
