Aditya‑L1, launched in September 2023, stays at a stable point between the Sun and Earth to continuously monitor the Sun.
The Visible Emission Line Coronagraph observed blue‑shifted and red‑shifted light, indicating plasma moving toward and away from the observer.
A three‑dimensional geometric‑kinematic model showed that an inclined eruption axis with asymmetric lateral expansion matched the observations, unlike a uniform expansion model.
These results help improve predictions of how Coronal Mass Ejections travel through the heliosphere and affect satellites, communication networks, and power grids.
Combined observations from Aditya‑L1’s Visible Emission Line Coronagraph, the United States Space Agency’s Solar Dynamics Observatory, and modeling by the Indian Institute of Astrophysics revealed a tilted eruption axis and non‑uniform lateral growth.
The asymmetric expansion influences the eruption’s speed and interaction with the solar wind, affecting the timing and intensity of space‑weather impacts on Earth’s technology.
