Executive Summary :

The Global Oscillation Network Group (GONG) instrument has been recording full disk images of the Sun since more than 20 years. This gives an opportunity to understand the long-term behavior of the Sun at least for 2 solar cycles. This project is aimed at developing an automatic detection technique for implementation on solar full disk images, extraction of features like sunspots and filaments and also estimating their attributes in consecutive images. This would help understanding the temporal evolution of the solar activity both on transient phenomena leading to eruptions and also on long term.
