G1 (Minor) Geomagnetic Storms Continue

G1 (Minor) Geomagnetic Storms Continue
published: Monday, December 21, 2015 12:25 UTC

G1 (Minor) to G2 (Moderate) geomagnetic storms dominated the field on 20 December through early on 21 December due to continued effects from the coronal mass ejection observed on 16 December. G1 (Minor) conditions are expected to continue through mid-day on 21 December as the solar wind environment remains enhanced along with a sustained southward magnetic field. Stay tuned for updates!
