A powerful geomagnetic storm is forecast to strike Earth on June 8, leading astronomers and skywatchers to carefully observe the sky for potential aurora displays. The incident has also brought back recollections of the unusual sighting of the Northern Lights over Ladakh in May 2024, when an intense solar storm created a spectacle rarely witnessed from Indian soil.
The US National Oceanic and Atmospheric Administration (NOAA) has announced a G3 (strong) geomagnetic storm watch following a coronal mass ejection (CME) from the Sun that is now on a trajectory toward Earth. Auroras, often called the Northern Lights, are natural light displays that occur when electrically charged particles released by the Sun interact with gases in Earth's upper atmosphere, producing colourful patterns across the night sky.
NOAA predicts strongest activity on June 8
The NOAA Space Weather Prediction Centre reports that the storm is forecast to intensify over a three-day period before gradually weakening. "Geomagnetic Storm Category G3 Predicted Highest Storm Level Predicted by Day: Jun 07: None (Below G1) Jun 08: G3 (Strong) Jun 09: G2 (Moderate) THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT," the warning read.
The approaching storm is forecast to engage with Earth’s magnetic field, which could produce striking auroras across high-latitude areas.
May 2024 in Ladakh
In an unusual and surprising event, auroras illuminated the night sky over Leh in Ladakh after a powerful geomagnetic storm struck Earth in May 2024. The phenomenon was observed from India’s highest observatory located in Hanle. Auroras are usually observed in higher latitudes, but the strength and frequency of this year’s solar storms have enabled the lights to appear much farther south in lower latitudes. In Leh, red auroral emissions were recorded using telescopes operated by India’s Department of Science and Technology.
Will India witness the phenomenon this time?
According to a report by TOI, the likelihood of witnessing auroras from India currently remains low. The approaching G3 geomagnetic storm is far less intense than the historic G5 event that lit up the skies over Ladakh in May 2024. Even so, astronomers and skywatchers will be watching closely.
