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 053 publicerat klockan 2200Z på 22 Feb 2012

IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z

Solar activity was very low. There were two B-class flares during the last 24 hours. The largest of these was a B5 at 1937Z from Region 1422 (N15W38). Region 1422 has shown steady decay during the period.
IB. Prognos för solaktivitet
Solar activity is expected to be very low. There is a chance, however, for an isolated C-class flare.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
The geomagnetic field has been at quiet to unsettled levels. A weak shock was observed at the ACE spacecraft at 22/0120Z and was followed by a sudden impulse of 20 nT at 22/0223Z at the Boulder magnetometer. Somewhat later in the day a solar sector boundary crossing was observed (22/0815Z) and was followed by a marked increase in solar wind velocity, indicative of the onset of a high speed stream from a coronal hole.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to be quiet to unsettled with a chance for isolated active periods during the next 24 hours as effects from the high speed stream persist. Predominantly quiet levels are expected for the second and third days (24-25 February).
