The Solar Ultraviolet Imaging Telescope (SUIT) is one of the seven payloads onboard the first solar dedicated mission of ISRO, called Aditya-L1. The spacecraft will be put in a halo orbit at the first Lagrangian point. SUIT will have a combination of narrow as well as broad filters and will be observing the Sun disk between 200-400nm by using 11 filters. SUIT will provide observations of the Sunís atmosphere from photosphere and chromosphere that will help understand the magnetic coupling of the two layers. In addition, for the first time we shall be able to measure the spatially resolved solar spectral irradiance in NUV, which is of prime importance for the Sunís influence on climate.
