Northern Lights tonight: Amazing spectacle to light up skies - HOW to see Aurora Borealis
2021-10-31 00:00:00.0     每日快报-科学     原网页

       A solar flare has erupted and is expected to reach the Earth on Saturday - triggering the stunningly beautiful Aurora Borealis across parts of the globe. Also known as the Northern Lights, these may be accompanied by a strong solar-magnetic storm which the National Oceanic and Atmospheric Administration (NOAA) has issued a warning for.

       The Northern Lights can be seen across the skies when massive levels of charged particles explode from the sun and come into contact with the Earth's magnetic field.

       These then react with gas molecules, giving off energy which creates the vibrant lights in the sky associated with the Northern Lights.

       Often Aurora Borealis can be seen across Norway and Iceland between late September and early March each year, however, solar events can bring them to other parts of the world - including the UK.

       So how can you watch the Northern Lights and will they be visible in the UK tonight?

       The Northern Lights are attracted to magnetic poles in both the Northern and Southern Hemispheres and so when visible in the UK they can be seen in the northern-most part of the UK - Scotland.

       However this weekend the lights will be visible further south than usual.

       Those in mid-Wales, the Midlands and parts of the East of England may be able to witness the spectacle on Saturday evening - when the Aurora reaches its peak.

       Weather forecasts are for clear skies for at least the first half of the evening, so sky gazers may be able to view the spectacle tonight.

       The Met Office has the following tips for seeing the Northern Lights

       Despite the beauty of the Aurora Borealis, it can also cause disruption.

       NOAA's warning cautions of issues to

       Power Systems

       - Voltage irregularities; false alarms on some protection devices

       Spacecraft

       - Surface changing; orientation problems; increased drag on low-Earth orbiters

       Radio and Navigation

       - Intermittent HF propagation fades. GNSS problems (loss-of-lock and increased range errors)

       Other

       - Aurora may be visible as low as Pennsylvania to Iowa to Oregon.
