- Scientists from the Indian Institute of Astrophysics observed coronal mass ejection (CME) driven shocks using the Gauribidanur radio telescope and the Visible Emission Line Coronagraph (VELC) onboard Aditya-L1.
- Visible Emission Line Coronagraph (VELC) is a payload designed to study the Sun’s corona in visible wavelengths.
- The Gauribidanur radio telescope operates below 150 MHz and observes low-frequency solar radio emissions.
- The team estimated that the CME-driven shock on May 27, 2024, began at about 130,000 km from the Sun.
- The shock was travelling at nearly 1,700 km per second near the Sun.
