We are expecting an increase in geomagnetic activity Sunday night due to increased solar activity.
A Coronal mass ejection (CME) left the Sun at approximately 09:00 UT on 4th May. It was associated with an M-class solar flare originating from an Earth-facing active region. This CME is expected to arrive late on 7th May or early on 8th and is likely to lead to an enhancement in geomagnetic activity, with a good chance of STORM periods.
The Sun has been quite active over the last few days, releasing many M-class solar flares and CMEs. Another M-class flare this morning (5th May) also had an associated CME, which may have an Earth-directed component. If this CME arrives shortly after the one from 4th May this could further increase and prolong the geomagnetic activity making more intense STORM periods possible.
Assuming clear dark skies, there is an increased chance of seeing the aurora on 7th-8th May. Those in Scotland, northern England and Northern Ireland have the best chance if the weather is favourable.
