India's first solar observation mission yields significant findings on coronal mass ejections, enhancing global understanding of solar phenomena.
Scientists in India have unveiled a critical milestone in their solar observation efforts with the Aditya-L1 mission, which is dedicated to studying the Sun's effects on Earth. On July 16, a significant result was achieved when the Visible Emission Line Coronagraph (Velc) onboard Aditya-L1 successfully recorded the precise onset of a coronal mass ejection (CME), a large expulsion of plasma and magnetic field from the Sun’s corona.
Coronal mass ejections can weigh as much as a trillion kilograms and travel outward from the Sun at astonishing speeds of up to 3,000 km (1,864 miles) per second, creating potential hazards for Earth and its technology. Prof. R. Ramesh of the Indian Institute of Astrophysics stated, “The event observed on July 16 initiated at 13:08 GMT. Although it was initially directed toward Earth, it subsequently diverted behind the Sun and posed no threat.”
Understanding CMEs is imperative not only for scientific exploration but also for safeguarding our technology. Although they rarely threaten human life directly, they can have serious implications. Solar storms can disrupt Earth’s magnetic field, leading to challenges for communication systems and power grid operations. “Our reliance on satellites makes us vulnerable; a significant CME could incapacitate internet, telephone, and radio communications,” cautioned Prof. Ramesh.
Highlighting this risk, he recalled the historical Carrington Event of 1859, a powerful solar storm that disrupted telegraph systems worldwide. More recently, in 2015, solar activity affected air traffic control across parts of Europe. Observations of solar phenomena allow for advanced warnings that could mitigate such impacts; scientists are aspiring to utilize Aditya-L1 data for more effective alerts.
As India enters this field, it joins the ranks of nations already monitoring solar dynamics, including NASA and the European Space Agency. From its position in space, Aditya-L1 can continuously observe the Sun, even during eclipses, enabling comprehensive studies of solar activity.
Prof. Ramesh emphasized the unique capabilities of Aditya-L1, particularly the Velc's design that offers a clearer view of the corona compared to other existing instruments, allowing for better real-time tracking of CMEs. Complemented by three ground-based observatories in India, the mission aims to significantly enhance our understanding of solar phenomena and their terrestrial repercussions.
As space weather becomes an increasingly pertinent global concern, India's contributions through the Aditya-L1 mission could potentially advance international efforts in space monitoring and weather preparedness.
