A spectacular display of auroras lit up the skies over Leh, India, as a severe geomagnetic storm struck Earth on October 10, 2024.
The auroras were captured at India’s highest observatory in Hanle.
This event was triggered by a powerful coronal mass ejection (CME) from the Sun, which reached Earth earlier today. The CME originated from an X1.8 solar flare that occurred on October 9, and it travelled at speeds exceeding 1.5 million miles per hour.
The National Oceanic and Atmospheric Administration (NOAA) classified the geomagnetic storm as G4, indicating severe conditions that could disrupt power grids and satellite operations.
Such storms can cause auroras to be visible much further south than usual, with reports suggesting sightings as far south as Alabama and northern California in the United States.

In Leh, the vibrant colours of the auroras created a breathtaking spectacle against the backdrop of the night sky.
The geomagnetic storm is part of an ongoing period of heightened solar activity as the Sun approaches its solar maximum, expected to peak in 2025.
This cycle has led to an increase in solar flares and CMEs, which are responsible for creating auroras when charged particles collide with Earth’s magnetic field.
The auroras observed in Leh were a direct result of these interactions, showcasing brilliant reds that captivated onlookers.
While the visual display was stunning, scientists warned of potential disruptions caused by the storm.
High-frequency radio communications were already experiencing interference, and there were concerns about impacts on satellite navigation systems.
Power companies and aviation authorities were advised to monitor conditions closely to mitigate any adverse effects.
As residents and tourists marvelled at the celestial light show, experts emphasised the importance of understanding space weather’s impact on technology and infrastructure.
This geomagnetic event shows our Sun’s dynamic nature and its influence on life on Earth.
