A full-halo Coronal mass ejection (CME), associated with an M-class solar flare, lifted from the Sun at approximately 19:12 UT on the 9th May. This is expected to arrive late on the 11th May or early on the 12th leading to likely enhanced geomagnetic activity.
Solar wind speeds remain slightly elevated after a CME arrival on 9th May which left the Sun on the 7th. Therefore, with this latest CME arrival, significant STORM periods are anticipated.
Assuming clear, dark skies, there is a greater chance of seeing the aurora on the 11th May through to the 12th May. Those in Scotland, northern England and Northern Ireland have a better chance if the weather is favourable on those nights.
