Coronal Mass Ejections (CMEs) Identification in Inner Solar Corona (CIISCO) algorithm will be used in India’s first solar mission, Aditya-L1. CIISCO was developed by the Aryabhatta Research Institute of observational sciences (ARIES) and Royal Observatory of Belgium.
This new algorithm will be used to detect and track the accelerating Coronal Mass Ejections (CMEs) in the lower corona of the Sun. Previously, Computer Aided CME Tracking Software (CACTus) based on a computer vision algorithm was used to detect and characterise such eruptions.
This vision algorithm detects the CMEs automatically in the outer corona where these eruptions cease to show accelerations and propagate with a nearly constant speed. However, this algorithm could not be applied to the inner corona observations due to the vast acceleration experienced by these eruptions.

Aditya-L1 Aditya-L1 Mission is India’s first solar mission planned by the Indian Space Research Organisation (ISRO). Earlier the name was Aditya -1, which has been renamed as Aditya-L1 Mission. It is ISRO’s second space-based astronomy mission after AstroSat for a scientific expedition to study the Sun. The mission was initially named Aditya 1 which was limited to observing only the solar corona.
Objective: is to study Sun’s Corona, Chromosphere and Photosphere. In addition, it will study the particle flux emanating from Sun, and the variation of magnetic field strength. Aditya L1 Mission
The main objective of the Aditya L1 Mission is that it will help in tracking Earth-directed storms and predict its impact through solar observations Why did ISRO Rename Aditya 1 Mission as Aditya L1 Mission? Aditya-1 mission was planned for observing only the Corona of Sun. The reason behind Corona getting heated to very high temperatures is still a mystery in Solar Physics. Aditya -1 mission involved placing the satellite in 800 Km low earth orbit. Later ISRO planned to place the satellite in the halo orbit around the Lagrangian Point (L1). L1 is 1.5 Million Km from the Earth. This point provides the advantage of observing the Sun continuously without any disturbance. Hence the mission was renamed as Aditya L1 mission. What is the Visible Emission Line Coronagraph (VELC)? It is an internally occluded solar coronagraph capable of simultaneous imaging, spectroscopy, and spectro-polarimetry close to the solar limb. What are the observations expected from Aditya L1? Observations on the following: Sun’s photosphere (soft and solid X-rays) Chromosphere (UV) and Corona (visual and NIR) |

India is now ranked 38th out of 139 nations in the Logistic Performance Index (LPI) 2023 of the World Bank. From its previous rankings of 44th in 2018 and 54th in 2014, this is a notable improvement. Earlier, the Logistics Ease Across Different States (LEADS) Report 2022 was published by the Ministry of Commerce and Industry. About Logi
Airports discovered more than 63% of this illegal gold. The Department of Revenue Intelligence recently conducted the Golden Dawn Operation across India, seizing 101.7 kg of illegal gold valued at Rs 51 crore. Despite the fact that India receives a legal import of about 800-1,000 tonnes of gold each year, the illicit market is thought to be
