Geomagnetic storm in progress
Image credit: TW
The geomagnetic field was unsettled to active at mid latitudes. Minor to major storm conditions occurred at high latitudes due to Coronal Hole (CH) high-speed stream (HSS) effects. Solar winds speeds were sustained above 620 km/s during the period. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.
