Rapport d'activité solaire
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.

Rapport de l'USAF/NOAA sur l'activité solaire et géophysique
SDF numéro 020 publié à 2200Z le 20 Jan 2001IA. Analyse des régions solaires actives et activité du 19-2100Z au 20-2100Z Solar activity has been moderate, another M flare was
observed from Region 9313 ( S07E41). This event, an M1/2f, began at
20/1834UTC and was accompanied by minor radio emissions, including a
type II sweep. The flare developed into parallel ribbons and the
filament running North from the region erupted during the event. A
CME was also observed. The leader spots of this region, although
small, are of mixed polarities resulting in a gamma magnetic
configuration. A new region appears to be rotating on to the disk
near S07. A small filament disappeared near S18 E09 sometime after
19/2137UTC.
IB. Prévisions d'activité solaire
Solar activity is expected to be low
to moderate. Additional M class flares are possible from Region
9313. In addition, several regions, including Region 9289 (S06
L=205) are due to return over the next couple days. Major flares
are possible if development in Region 9313 continues or if these
regions return active.
IIA. Résumé de l'activité géophysique du 19-2100Z au 20-2100Z
The geomagnetic field has been mostly quiet to unsettled. A brief
period of active conditions occurred around 0900UTC.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be generally quiet to unsettled early in the period.
There is a good chance of active conditions later in the period as a
result of recent activity in Region 9313.
