A large coronal has rotated around the Sun to an Earth-facing position. This morning the solar wind speed increased, marking the arrival of the coronal hole's high speed solar wind stream. Since it's arrival there have been stormy geomagnetic conditions, reaching STORM G2 before midday today (27th March).
This coronal hole has faced the Earth before and caused several STORM G1 periods, and an isolated G2 period. The coronal hole does not appear to have decreased in size, so it is likely to cause a similar elevation in geomagnetic activity again. Activity may peak over the night of 27th-28th March, but STORM periods are expected for the next 2-3 days.
Assuming clear dark skies, there is an increased chance of seeing the aurora, particularly for those in Scotland, northern England and Northern Ireland.
