Solaktivitetsrapport

Föregående rotation Föregående dag Kalender

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 174 publicerat klockan 2200Z på 23 Jun 2003

IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z

Solar activity was low due to a single C1/Sf flare from Region 388 (S01W47) at 22/2148Z. Regions 386 (S07W22), 387 (N17W03), and 388 exhibited little change this period and produced no significant activity. A new region emerged to the south of Region 387 and was numbered 391 (N15E03).
IB. Prognos för solaktivitet
Solar activity is expected to continue at low levels. There is a slight chance for a low M-class flare primarily from Region 386.
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
The geomagnetic field was unsettled to active with an isolated minor storm period between 23/03-06Z. The field was disturbed due to a high speed coronal hole stream which peaked near 600 km/s very early in the period and has been in slow decline since. The greater than 2 MeV electrons reached high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to be primarily unsettled with isolated active periods.

Comments K-indicies The scaling problem with the Boulder magnetometer instrument has been fixed and the instrument has been redesignated as the primary instrument for Boulder K-indices. GOES Protons To ensure continued operational monitoring of important energetic particle data, it is necessary to reassign primary/secondary designations for the GOES Space Environment Monitor (SEM) detectors. GOES 11 (113W) is now the primary satellite for protons. GOES 12 will continue as the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 (135W) will be the secondary satellite for all SEM sensors - magnetometer, X-ray, and energetic particles. Because of the degraded state of the proton data on GOES-10, its designation as the secondary source for proton data is a short-term solution. More permanent solutions have been identified and are being evaluated. Users will be notified when we define and schedule a permanent fix. Further details can be found at http://www.sec.noaa.gov/GOES.html.
