Aditya-L1 and Doppler imaging of solar eruptions
Quick dive
- The Visible Emission Line Coronagraph (VELC) is a payload on Aditya-L1.
- Scientists generated Doppler velocity images of the solar corona.
- Positive and negative Doppler velocities indicate plasma moving away from and towards the observer.
- The images may help infer the propagation direction of coronal mass ejections along the Sun-Earth direction.
- exam_relevance: turns the mission into a precise conceptual question on Doppler effect, corona, CMEs and space weather, with a mission-specific instrument and scientific application rather than a launch fact.
