• Scientists from Aryabhatta Research Institute of observational sciences (ARIES) have developed an algorithm, CMEs Identification in Inner Solar Corona (CUSCO) to detect and track CMEs in lower corona.
• The parameters determined by CUSCO are useful to characterise these eruptions in the lower corona, a region where the properties of such eruptions are less known.
• ARIES, Nainital, is an autonomous institute under Department of Science and Technology.
• CME is a giant cloud of solar plasma drenched with magnetic field lines that is blown away from the Sun often during strong, long-duration solar flares and filament eruptions.
• A CME contains particle radiation (mostly protons and electrons) and powerful magnetic fields. They cause disruption of space weather and satellite failures, and power outages, etc.
• Computer Aided CME Tracking Software (CACTus) was used to detect and characterise such eruptions automatically in the outer corona.
• However, this algorithm could not be applied to the inner corona observations due to the vast acceleration experienced by these eruptions.
• As India’s first solar mission, Aditya-LI, will be observing this region of the solar corona, implementation of CIISCO on the Aditya-L1 data will provide new insight into the CME properties in this less explored region.
