Abstract:
The Solar Ultraviolet Imaging Telescope (SUIT) is an instrument onboard the Aditya-L1 spacecraft, the first
dedicated solar mission of the Indian Space Research Organization (ISRO), which will be put in a halo orbit at
the Sun-Earth Langrage point (L1). SUIT has an off-axis Ritchey–Chrétien configuration with a combination of
11 narrow and broad bandpass filters which will be used for full-disk solar imaging in the Ultravoilet (UV)
wavelength range 200-400 nm. It will provide near simultaneous observations of lower and middle layers of the
solar atmosphere, namely the Photosphere and Chromosphere. These observations will help to improve our
understanding of coupling and dynamics of various layers of the solar atmosphere, mechanisms responsible for
stability, dynamics and eruption of solar prominences and Coronal Mass ejections, and possible causes of solar
irradiance variability in the Near and Middle UV regions, which is of central interest for assessing the Sun’s
influence on climate.
