Perustelut ennusteille

AihePerustelu (päivitetty viimeksi 2.2.2023 kello 02:30)
Auringon aktiivisuusSolar activity is expected to be low, with a slight chance for M-class flares (R1-R2 Minor-Moderate) on 02-04 Feb, mostly due to activity from Region 3207.
AurinkotuuliPeriodic enhancements in the solar wind parameters are possible on 02 Feb with suspected CH HSS influence. Late on 03 Feb, CH HSS effects are expected to begin a gradual decline, returning to a more background-like state by late 03 Feb/early 04 Feb.
Geomagneettinen kenttäThe geomagnetic field is expected to be mostly quiet to unsettled, with isolated active periods, on 02 Feb. By 03 Feb, activity is expected to gradually diminish as negative polarity CH HSS gradually subsides.
