Weather forecasters say it is touch and go whether or not the Northern Lights will be visible from Portsmouth tonight.
A large solar storm resulted in the aurora borealis being seen as far south as the south coast of England on Monday night and the Met Office says there could be more aurora views tonight - provided cloud clears in time.
The Met Office blog added: “Large geomagnetic storms can result in disruption to power grids, which is why it is important that these storms are monitored and warned for, although fortunately the UK grid is more resilient to space weather than the grids in many other countries.
“There are no impacts on human health as a result of these solar storms, in fact they can have some very welcome effects in the form of increased aurora, both in effect and extent.”
Met Office Space Weather advisors are now watching more solar activity which could bring more spectacular aurora views on Wednesday night.
The Met Office blog adds: “To see the northern lights, wait until at least half an hour after sunset, go outside away from artificial lights, let your eyes accustom to the dark and look towards the north.”
The Met Office forceast for the Portsmouth area tonight is: ‘Fairly cloudy at first with some outbreaks of rain possible but clear spells developing later in the night. Winds remaining light. ‘
