The Met Office has said the Northern Lights could again be visible in parts of the UK over the next few days following a geomagnetic storm.
It may be possible to catch sight of the aurora after the storm this week.
A geomagnetic storm is a major disturbance of the Earth's magnetosphere. It occurs due to an efficient exchange of energy from the solar wind into the environment surrounding Earth.
News of further coronal mass ejections (the phenomenon causing the Northern Lights) which increase the visibility the auroral oval, follows huge displays of the lights across the UK and parts of Europe during May.
They were enhanced by an “extreme” geomagnetic storm.
While the storm hitting Earth this week has not been given a G5 rating, aurora sightings may again be possible across parts of the UK from Monday evening - and may be clearest in Scotland.
Solar activity and a magnetic storm could be strong enough to knock out some radio signals.
The Met Office said of the G3 storm: “The auroral oval may become enhanced Monday night into Tuesday from the impact of a Coronal Mass Ejection.
“Aurora sightings may become visible in Scotland although impeded by limited hours of darkness.”
According to the southern hemisphere forecast, the south of Tasmania may also come into view of the northern lights.
Low cloud cover generally provides a better viewing experience as people have previously been advised to look for the lights under a “clear sky”.
