G2 (Moderate) Geomagnetic Storm Watch for 10 Sep
published: Wednesday, September 11, 2024 12:10 UTC

CME influences from a filament eruption that occurred early on 8 Sep will arrive by midday on 10 Sep (UTC) and will likely cause moderate geomagnetic storming effects. Any geomagnetic storming effects that linger into 11 Sep (UTC) will likely taper off into minor storming levels.
