Coronal Green-Line Emission During a Solar Prominence Eruption: Spectroscopic Evidence of Its Correspondence with the EUV Late Phase
P. Vemareddy, R. Ramesh, V. Muttu Priyal
We report spectroscopic observations during a prominence eruption on 9 October 2025 from the Sun's west limb, associated with an M2.0 flare that commenced at 12:11 UT. The event wa…
Coordinated Coronagraphic Observations from Proba-3 and Aditya-L1: Investigating CME Energetics in the Inner Corona
Anjali Agarwal, Wageesh Mishra, R. Ramesh +16
Constraining the plasma properties and energetics of coronal mass ejections (CMEs) in the inner corona is essential for understanding their early evolution, yet remains challenging…
Aditya-L1/VELC observations of CME associated broadening of 5303Å coronal emission line
K. Sasikumar Raja, V. Muthu Priyal, R. Ramesh +2
We present Aditya-L1/VELC spectroscopic observations of 5303Å coronal emission line widths before and after coronal mass ejections (CMEs) which showed coronal dimming. The sit \& s…
A consistency check for the calibration of 5303Å 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 5303Å using observations of the Sun itself, a novel approach compared to…
