A consistency check for the calibration of 5303Ã solar coronal emission line observations with Aditya-L1/VELC
V. Muthu Priyal, R. Ramesh, Jagdev Singh +2
We carried out radiometric calibration of the Visible Emission Line Coronagraph (VELC) onboard Aditya-L1 at 5303Ã using observations of the Sun itself, a novel approach compared to…

Constraining the onset height of coronal mass ejection driven shocks using near-Sun observations in visible and radio wavelengths
C. Kathiravan, V. Muthupriyal, R. Ramesh
One of the debated issues about the onset of the type II radio bursts near the Sun is the heliocentric distance () at which the associated magnetohydrodynamic (MHD) shocks are f…

New Results on the Onset of a Coronal Mass Ejection from 5303 Ã Emission Line Observations with VELC/ADITYA-L1
R. Ramesh, V. Muthu Priyal, Jagdev Singh +3
We report on the onset of a coronal mass ejection (CME) using spectroscopic observations in 5303 Ã coronal emission line with the Visible Emission Line Coronagraph (VELC) onboard A…
