The forefront of solar research is now being led by the Aditya-L1 mission, India’s pioneering endeavor in solar observation. Launched on September 2, 2023, this state-of-the-art spacecraft orbits around the first Sun-Earth Lagrange Point (L1), approximately 1.5 million kilometers from our planet, providing an exceptional vantage point to study the Sun’s behavior in unprecedented detail.
In a significant breakthrough, researchers utilized the spacecraft’s specialized instrument, the Visible Emission Line Coronagraph (VELC), to capture the dynamics of a Coronal Mass Ejection (CME) that accompanied a powerful solar flare on July 16, 2024. This instrument was able to analyze the Sun’s outer atmosphere, which showcased temperatures soaring beyond one million degrees Celsius. During the CME, a phenomenon known as “coronal dimming” was observed, revealing a 50 percent reduction in brightness in a sunspot region, lasting around six hours.
This CME event not only elevated surrounding temperatures by 30 percent but also stirred up turbulence in the plasma surrounding the Sun, propelling it at an astonishing speed of nearly 25 km/s. These patterns demonstrate the Sun’s magnetic activity during this event, crucial for understanding how CMEs interact with its magnetic fields.
Overall, the Aditya-L1 mission is making groundbreaking contributions to solar science, shedding light on the mysteries of the Sun’s atmosphere and its effects on space weather, paving the way for future explorations in this volatile domain.
