23 September 2021 Current Affairs:A recent study shows how Sun’s coronal mass ejections influence the accuracy of space weather prediction, which is crucial for the health of our satellites.

Highlights:
♦ A recent study has shown that within the solar atmosphere like coronal mass ejections influence the accuracy of space weather prediction, which is crucial for the health of our satellites.
♦ This understanding will aid the interpretation of information from the upcoming Aditya-L1, India’s first solar mission.
♦ Space weather refers to the conditions within the solar radiation and near-Earth space, which might adversely affect the performance of space-borne and ground-based technological systems.
♦ The space weather near the planet is principal because of Coronal Mass Ejections (CMEs), which are frequent explosive expulsions of giant magnetized plasma from the Sun into its surroundings, which might blow past the planet.
♦ An example of space weather events is the geomagnetic storm, a perturbation within the Earth’s magnetic flux, which might last for a few hours to a few days.
♦ Plasma properties and Earth arrival times of CMEs from the Sun vary substantially with longitudinal locations within the interplanetary space. Sun emits an endless stream of charged particles called solar radiation.
♦ The study highlights the difficulties in connecting the local observations of an ICME from one in-place spacecraft to its global structures. 
♦It explains that accurate prediction of enormous CME structures at any location within the heliosphere is challenging. Ce weather prediction, which is crucial for the health of our satellites.
