Comparative 3D Asymmetric Expansion and Angular Widths Evolution of Fast and Slow Coronal Mass Ejections
Anjali Agarwal, Wageesh Mishra, Jie Zhang +2
The radial and lateral dimensions of coronal mass ejections (CMEs) influence their duration and probability of encounter at Earth. These properties are linked to the expansion spee…
Three-Phase Evolution of Aspect Ratio in Fast and Slow CMEs from the Sun to 1 AU
Wageesh Mishra, Anjali Agarwal, Nandita Srivastava
Coronal mass ejections (CMEs) undergo significant geometric evolution as they propagate from the Sun to 1 AU, influencing their radial size, expansion, and space weather impact. We…
Validating a Non-conventional Method for Expansion of Coronal Mass Ejections (CMEs) and Investigating the Evolution of a CME Substructures Using Solar Orbiter and Wind Observations
Anjali Agarwal, Wageesh Mishra, Mathew J. Owens +1
We present a validation of our recently proposed non-conventional method, Constant Acceleration Accounted Perspective (CAAP), for estimating the instantaneous expansion speed of co…
Evolution of interacting coronal mass ejections driving the great geomagnetic storm on 10 May 2024
Soumyaranjan Khuntia, Wageesh Mishra, Anjali Agarwal
The arrival of a series of coronal mass ejections (CMEs) at the Earth resulted in a great geomagnetic storm on 10 May 2024, the strongest storm in the last two decades. We investig…
Disparities in Magnetic Cloud Observations Between Two Spacecraft Having Small Radial and Angular Separations Near 1 AU
Anjali Agarwal, Wageesh Mishra
Studies for inferring the global characteristics of coronal mass ejections (CMEs) from its multipoint local in situ observations have been undertaken earlier, but there are limited…
Non-conventional Approach for Deriving the Radial Sizes of Coronal Mass Ejections at Different Instances: Discrepancies in the Estimates Between Remote and In Situ Observations
Anjali Agarwal, Wageesh Mishra
Understanding the evolution of radial sizes and instantaneous expansion speeds of coronal mass ejections (CMEs) is crucial for assessing their impact duration on Earth's environmen…
