A CME that erupted from the Sun last Saturday (6 June) is expected to arrive today (8 June). This could lead to significant geomagnetic activity reaching STORM G3 levels. Increased chances of seeing the aurora tonight (8–9 June)! More details at: https://t.co/451J466aQW

[BGS Aurora Alert @BGSauroraAlert]

Three CMEs erupted from the Sun yesterday, 2 of which are expected to arrive later today. This will likely lead to significant geomagnetic activity to STORM levels. Increased chances of seeing the aurora tonight 4th June! More details at: https://t.co/nJxikoLOGX

[BGS Aurora Alert @BGSauroraAlert]

Several CMEs observed between 16-18 March are expected to arrive over the next couple of days and lead to elevated geomagnetic activity. Increased chances of seeing the aurora between 19-21 March! More details at https://t.co/vQ6Drj5eSn

It looks like a CME has just arrived, geomagnetic activity is ramping up in response so #aurora sightings are likely if you're under clear dark skies

[BGS Aurora Alert @BGSauroraAlert]

Coronal mass ejection observed in the evening on 06 Dec is expected to arrive tonight (08-09 Dec)! Anticipated geomagnetic storm conditions will increase the chances of seeing the aurora, particularly at high latitudes.

UK braced for what could be the largest solar storm in over two decades.

Reports of aurora overnight due to the STORM G4 geomagnetic storm. Another X5.1 full halo CME is on the way leading to possible STORM G5 conditions. Aurora sightings likely tonight assuming some clear skies.

[BGS Aurora Alert @BGSauroraAlert]

The anticipated coronal mass ejections have arrived. A geomagnetic storm is expected over the coming hours if conditions persist. Aurora sightings are possible.

[BGS Aurora Alert @BGSauroraAlert]

STORM expected this evening and over the coming days. Two incoming Coronal Mass Ejections (CMEs) later today and into tomorrow will result in enhanced geomagnetic conditions. Aurora may be visible with clear dark skies, especially northern UK.

Solar activity is high and there is an increased chance of significant geomagnetic activity over the next few days. This could lead to opportunities for aurora sightings.

[BGS Aurora Alert @BGSauroraAlert]

STORM in progress, aurora may be visible with clear dark skies

STORM expected on Friday.
We are expecting an incoming Coronal Mass Ejection (CME) combined with a high-speed stream from a coronal hole. These conditions will enhance the solar wind speed, and geomagnetic STORM periods are likely to follow.
