A CME hit Earth’s magnetic field on Nov. 29th (0245 UT), but the impact was so weak it did not spark a geomagnetic storm. The G2-storm watch previously issued for Nov. 29th is cancelled

A G2-class geomagnetic stom is possible on Nov. 28th when a CME is expected to hit Earth’s magnetic field. The CME was hurled into space by a magnetic filament attached to sunspot 3901, which erupted on Nov. 25th. There is a chance this CME will sail south of Earth with little to no contact, so this is a low probability forecast.
