Geomagnetic Disturbance Alert

25th October 2016

British Geological Survey

A very large centrally located coronal hole has rotated around the Sun to an Earth-facing position. The Earth is now under the influence of the coronal hole's high-speed solar wind stream that arrived this morning.

This solar wind stream is expected to elevate geomagnetic activity levels for several days. Activity may peak over the night of the 25th - 26th but periods of heightened geomagnetic activity are expected over the next few days.

Assuming clear dark skies, and a continuation of geomagnetic storming, there is an increased chance of seeing the aurora. For those in the UK those in Scotland, northern England and Northern Ireland may have the best opportunities.
