The heightened chance of a UK sighting has been caused by a fast-moving coronal mass ejection, which is a "release of plasma and magnetic field from the Sun's corona", late on Saturday night.

Scientists hope that as the spacecraft passed through our star's outer atmosphere - its corona - it will have collected data that will solve a long-standing mystery.

By doing this, the scientists hope to learn more about the super-heated gases that comprise the solar corona.

Studying CMEs – massive fireballs that blow out of the Sun’s outermost corona layer – is one of the most important scientific objectives of India’s maiden solar mission.
