Powerful Solar Flare & Geomagnetic Storm May Bring Auroras to the UK Tomorrow!
9th Oct 2024
A powerful X1.8 solar flare erupted from the Sun at 01:56 UTC on 9th October, 2024, launching a significant coronal mass ejection (CME) directly towards Earth. This event has space weather experts on high alert and could lead to an opportunity for UK residents to witness the Northern Lights.
Severe geomagnetic storm
Earth-facing sunspot region 3848 produced a long-duration X1.8 solar flare, classified as R3-strong. The flare’s perfect Earth-facing position suggests a high likelihood of impact. Key indicators include:
- Type II and IV radio emissions detected
- Coronal dimming observed
- S3 solar radiation storm in progress (only the second of this magnitude in the current solar cycle)
What to Expect

The NOAA Space Weather Prediction Center has issued a G4 (severe) or greater geomagnetic storm watch. This indicates the potential for a Kp index of 8 or even 9, rivaling the extreme geomagnetic storm experienced in May 2024.
Timing
The fast-moving CME could reach Earth as early as Thursday evening, 10th October. Current projections estimate impact around 17:00 UTC.
Aurora Potential for the UK
This event presents an opportunity for UK residents to witness the Northern Lights. During similar storms, auroras have been visible overhead from locations as far south as England. Even areas that typically don’t experience auroral displays may have a chance to see this celestial spectacle.
How to Prepare
- Keep your devices charged
- Monitor space weather alerts and forecasts
- Plan to be away from city lights on Thursday night
- Have cameras ready for potential photography opportunities
Stay Informed
This is a rapidly evolving situation. We recommend keeping a close eye on updates from reliable space weather sources and local astronomy groups for the most current information on viewing possibilities in your area. Remember, while the potential for a spectacular display is high, space weather predictions can be uncertain. Be prepared, but also patient, as nature delivers this cosmic show.
