People in the UK may be treated to a spectacular natural display tonight if the Northern Lights appear over the isles.
Scientists have tipped tonight - the day before Halloween - to be a magical one thanks to solar flares.
A huge burst of radiation from the sun on October 28 is due to reach the Earth tonight after a 92 million mile journey.
The cloud of electromagnetic particles will cause a colourful display in the atmosphere which may be visible from parts of the Northern Hemisphere.

The best vantage points will fall across Iceland, Scotland, Norway, Alaska, Canada and Michigan in the US, C Alex Young, NASA's Heliophysics Division associate director at the Goddard Space Flight Centre in Maryland, said.
The best chance of seeing the phenomenon will be around 12am, when it is usually the darkest.
Luckily the Met Office has forecasted that there will be little to no cloud cover tonight, meaning the view won't be blocked.
The Northern Lights tend to shine brightest the further north you are, meaning those in the south of England probably won't get much of a display.
This is primarily because the planet's poles conduct the most electromagnetic energy.
The solar discharge could impact some of the planet's orbiting satellite arrays, meaning some mobile devices may stop working temporarily.
When the Sun first loosed its latest flare, it caused a near-immediate impact in South America.
Most of the continent, at the time facing the star, briefly lost radio capabilities.
Solar flares are divided into categories according to their strength and the one that was fired off on Thursday was an X1-class.
They are classified in a letter system, with C-class being relatively weak, M-class moderate and X-class flares as the strongest.
Among X-class ones, “an X2 is twice as intense as an X1, an X3 is three times as intense”, according to NASA.
The one currently headed towards Earth is an X1 flare which, despite being the least intense of the X-class flares, is likely wreak havoc by interfering with radio and satellite communications.
