UK Aurora Alerts & Northern Lights Forecast
Explore current aurora conditions across Britain and
official NOAA geomagnetic storm forecasts.
Understanding the Northern Lights Forecast
The Northern Lights, also called the aurora borealis,
occur when charged particles from space interact with
Earth's magnetic field and upper atmosphere.
Stronger geomagnetic activity can allow auroras to
become visible further south across the United Kingdom.
What does the Kp index mean?
The planetary Kp index measures geomagnetic disturbance
on a scale from 0 to 9. Higher values generally indicate
stronger geomagnetic activity. However, Kp alone cannot
guarantee that the Northern Lights will be visible
from a particular location.
What are G1–G5 solar storm levels?
NOAA classifies geomagnetic storms from G1 (minor)
to G5 (extreme). G1 begins at Kp 5, while G5
corresponds to Kp 9. Stronger storms may allow
auroras to reach lower latitudes.
Where can I see the Northern Lights in the UK?
Northern Scotland generally offers the best opportunities.
During stronger geomagnetic activity, auroras may also
become visible from northern England, Wales, the Midlands
and occasionally southern England.
Why might the aurora not be visible?
Even when aurora activity is forecast, visibility depends
on darkness, cloud cover, light pollution, the direction
of the auroral display and actual geomagnetic conditions.
A forecast indicates potential activity, not a guaranteed
sighting.
