Scientists develop new technique to track solar eruptions and to be used in India’s first solar missionSolar Physicists of ARIES (Aryabhatta Research Institute of Observational Sciences), Nainital, Uttarakhand have developed a New Algorithm called ‘CIISCO’ (CMEs Identification in Inner Solar Corona) for detecting & tracking the accelerating solar eruption in the lower/inner corona of the Sun.  The algorithm will be used in India’s 1st Solar Mission – Aditya – L1 (set to be launched in 2022).

  • The ejections from the sun are technically called Coronal Mass Ejections (CMEs).
  • A Research team led by Mr. Ritesh Patel, Dr. Vaibhav Pant, and Professor Dipankar Banerjee from ARIES collaborated with the Royal Observatory of Belgium for the development of the Algorithm.
  • Aditya-L1 will be observing the inner corona region, hence the implementation of CIISCO on the Aditya-L1 data will provide new insight into the properties of CME.
  • The research has been published in the ‘Solar Physics’ Journal.

Coronal Mass Ejections (CMEs)

  • CMEs are composed of Plasma & Magnetic fields.
  • Forecasting their arrival is important as they have the capacity to cause disruptions in space weather, geomagnetic storms, satellite failures, and power outages.
  • Earlier, Scientists used a software called Computer Aided CME Tracking Software (CACTus) for detecting eruptions in the outer corona. However, this algorithm cannot be applied to inner corona observations.
  • CIISCO has already been tested on several eruptions observed by space observatories Solar Dynamics Observatory & Solar-Terrestrial Relations Observatory, PROBA2 & SWAP launched by U.S. Space Agency NASA & European Space Agency (ESA), respectively.


  • The First Solar Mission of India is expected to be launched in 2022.
  • It is being built in collaboration between the Indian Space Research Organisation (ISRO) & various Indian research institutes.
