India, Jan. 30 -- The Government of India issued the following news release:
A novel method has been found to determine the instantaneous expansion speed and radial size of Coronal Mass Ejections (CMEs) from the Sun when it passes over a spacecraft at a single-point in the interplanetary medium.
The radial dimension of CMEs governs the longevity of the CMEs and their associated geomagnetic storms on the Earth and hence it is important to determine it, to predict the influence of the CMEs on the Earth's communication system.
CMEs are magnetized plasma bubbles ejected from the Sun and evolve in the interplanetary medium. They are the major drivers of perturbations in the Earth's magnetic field, known as geomagnetic storms. Such storms can ...
