| Abstract : | The Solar Ultraviolet Imaging Telescope (SUIT) is an off-axis Ritchey-Chrétien solar telescope onboard Aditya-L1, India’s first and upcoming dedicated solar observatory in space. Aditya-L1 will be placed at a halo orbit around the Lagrange point L1 of the Sun-Earth system to observe the Sun. SUIT will study the Sun in near-ultraviolet (NUV; 200nm to 400nm) spectral range using eight narrowband and three broadband filters with high contrast images, good spatial resolution (~1.5 arcsec ) and high cadence. The scientific goals of SUIT are primarily to study four areas, viz. 1. Near simultaneous observations and study of coupling and dynamics in the solar atmosphere from the photosphere to the upper chromosphere; 2. Detailed study of Prominences, filaments and their dynamics in NUV spectral range; 3. Study of Solar flares, especially their effect in the chromosphere and to capture the early phases of the flare trigger, which will help to understand the early phase kinematics of coronal mass eruptions; 4. Study of Sun-Earth connections concerning Earth’s climate, the effect of UV irradiance variation on Earth’s upper atmosphere chemistry, etc. This presentation will explain the SUIT instrument design, specifications, capabilities, data formats, and how these will help address the primary science goals. SUIT will help us better understand the Sun's physics along with data from other solar observatories like SDO, Hinode, DKIST and MAST. This will enable us to strongly establish our scientific conclusions and provide a multiwavelength insight of the Sun. |
