Yahoo News Northern Lights alert issued as display could be visible in UK again TONIGHT
The Northern Lights could be visible in large parts of the UK again tonight.
Scientists at Aurora Watch UK have issued a red alert that we could see the spectacular displays once more this evening on Saturday (May 18).
Scientists from the Space and Planetary Physics group at Lancaster University’s Department of Physics said: "Aurora is likely to be visible by eye from Scotland, northern England and Northern Ireland; possibly visible from elsewhere in the UK. Photographs of aurora are likely from anywhere in the UK."

Last week the Aurora Borealis was visible across the whole country as solar radiation crashed into the Earth's atmosphere, creating shimmering sheets of green, pink and purple light in the night sky.
The Met Office space weather unit said: “Enhancement to the aurora is likely into early May 18,” adding: "The aurora may become visible as far south as parts of Scotland where skies are clear. Mainly background aurora conditions are expected thereafter."
The US National Oceanic and Atmospheric Administration (NOAA) said a G5 geomagnetic storm has been created by a "large, complex" sunspot cluster 17 times the diameter of earth. A solar storm this powerful has not been seen for more than 20 years.
Tonight could be the last display of the current storm, but the BBC reports another solar blast is expected in two weeks when the sunspot that created the Northern Lights rotates back towards the Earth.
The Sun is approaching what is called "solar maximum" - a point during an 11-year cycle when its activity is strongest, Wales Online reports.
The storms are usually most visible in the early hours of the morning. They can be spotted any time from when the sky is dark but are easiest to see at around 2am or 3am. Setting your camera to night mode will ensure the best possible pictures.
How to see the Northern Lights:
Move Away from Light Pollution: Find a spot away from city lights. National parks and remote areas are ideal.
Be Patient and Prepared: Dress warmly, as you'll be outside in cold conditions for several hours. Bring snacks, a hot drink, and a blanket or portable chair.
Photography Tips:
Use a camera with manual settings.
Set a low aperture (f/2.8 or lower).
Use a high ISO setting (800-3200).
Set a long exposure time (10-25 seconds).
Use a tripod to keep your camera steady.
