A full-halo Coronal Mass Ejection (CME) erupted from the Sun at approximately 05:20UT on 11th April. It was associated with a filament lifting off from an Earth-facing active region in the southeast quadrant. This CME is predicted to arrive in the second half of 14th April.
Geomagnetic activity has already been enhanced during the last 24 hours by the arrival of a CME that left the Sun on 9th April, also associated with a filament. If the CME from 11th April arrives whilst the solar wind remains disturbed this could lead to significant disturbances to the geomagnetic field, with an outside chance for geomagnetic conditions to reach STORM G3 levels, although STORM G2 is more likely.
Assuming clear, dark skies, there is a greater chance of seeing the aurora on 14th April. Those in Scotland, northern England and Northern Ireland have a better chance, if the weather is favourable on 14th April.
