Travellers in Ladakh were in for a surprise when the skies were set ablaze in colourful lights as a strong geomagnetic storm struck Earth's magnetic fields, thereby creating unreal auroras.

Auroras are usually witnessed at higher altitudes in parts of Norway, Alaska, and other countries.

The aurora was captured on the night of April 22-23 after a coronal mass ejection was hurtled from the Sun on April 21.

Wageesh Mishra, Assistant Professor at the Indian Institute of Astrophysics, added that the CME struck the Earth at a speed of 21,60,000 km per hour.
