How a new tracking index could save satellites and astronauts in space
India Today2024 will not only be remembered for extreme weather events, but also for powerful solar eruptions from the Sun that triggered stunning auroras across the world including in India's Ladakh. The disruption in the Earth's magnetic field was so intense that Isro and other global space agencies had to take pre-emptive measures to ensure safety of their satellites. Researchers have now developed a new index to offer a near real-time global perspective on geomagnetic variations, enabling the local effects of space weather events. These charged particles when collide with Earth's magnetic field, trigger stunning auroras seen not only from space but also from the land. Swarm satellites measure changes in Earth’s magnetic field from space, and can capture geomagnetic anomalies related to space weather all over the world.
