The recent visibility of the Northern Lights in southern UK regions can be attributed to significant coronal mass ejections, expanding the reach of the auroras southward.
Prof Jim Wild noted that larger coronal mass ejections from the Sun result in broader area visibility, making sightings possible as far south as the Caribbean.
The diverse colors of the Northern Lights, including green and hints of purple, blue, or pink, are due to various gases like oxygen and nitrogen burning.
Increased activity from the Sun, including the number of sunspots on an 11-year cycle, affects the visibility of the Northern Lights, contributing to recent sightings.
