BGS Aurora Alert

Keep track of current global geomagnetic activity levels here: geomag.bgs.ac.uk/data_service/s…

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 geomag.bgs.ac.uk/data_service/s…

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

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. 📽️ Animation of SOHO LASCO Coronograph imagery showing the coronal mass ejection (CME) associated with the X5 solar flare. The scintillation is due to energetic particles hitting the sensor (NASA/ESA).

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.

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

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.

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.

Next 48 hrs - STORM. Expecting two incoming coronal mass ejections ( CME ) from two filament eruptions over the last weekend. These predicted to arrive later today or early on 16. STORM periods are likely to follow.

Next 48hrs: Increased chance of seeing the aurora tonight and tomorrow night (15th-16th April). Assuming clear, dark skies those in Scotland, northern England and Northern Ireland have the best chance. Keep track of current geomagnetic activity here: geomag.bgs.ac.uk/data_service/s…

Next 48hrs: Increased chance of seeing the #aurora over the weekend due to incoming solar activity. A coronal mass ejection (CME) is expected late 22 or early 23 (GMT/UT). Keep track of current activity: geomag.bgs.ac.uk/data_service/s…

There are confirmed sightings of the aurora around the UK right now. If you have clear skies in your area then look up and you might just get a display of the Northern Lights to welcome in 2025! Aurora activity update via: geomag.bgs.ac.uk/education/curr… 📷: @mgs_geog

Next 24 hrs: Increased chance of seeing the aurora during 31 Dec-01 Jan due to enhanced geomagnetic conditions caused by two possible CME arrivals. Assuming clear, dark skies, those in Scotland, northern England and Northern Ireland have the best chance. Happy New Year!

Next 24 hrs - ACTIVE. Two Coronal Mass Ejections are heading our way and could increase geomagnetic activity up to STORM G2 levels with a slight chance of isolated STORM G3 periods.
