Sankarasubramanian<br>Indian Space Research Organisation (ISRO) <br><br>Abstract:<br></div><div>The first Indian Solar and Heliospheric Observatory, Aditya-L1, was launched on 2nd September 2023. It successfully reached the intended L1 orbit on the 6th January 2024. The mission is currently in science operation phase providing unique science data. The primary science objective of the mission is to understand the solar dynamics,<br></div><div>especially the chromospheric and coronal dynamics of the Sun and its influence at L1 which in turn provides information about the disturbances which potentially reaches Earth. To accomplish this, Aditya-L1 is configured with four remote sensing and three in-situ experiments. The remote sensing experiments include: (i) Visible Emission Line Coronagraph (VELC), (ii) Solar Ultra-violet Imaging Telescope (SUIT), (iii) Solar Low-Energy X-ray Spectrometer (SoLEXS), and (iv) High Energy L1 Orbiting Spectrometer (HEL1OS). Along with the remote sensing payloads, there are three in-situ experiments to measure the in-situ particles and magnetic field dynamics. The in-situ experiments are: (i) Plasma Analyser Package for Aditya-L1 (PAPA), (ii) Aditya Solarwind Particle EXperiment (ASPEX), and (iii) MAGnetometer (MAG). In this presentation, Aditya-L1's science capabilities as a stand-alone mission and also synergetic with other missions or observatories will be highlighted. A glimpse of Aditya-L1's science capabilities from the science observations so far will be presented. As an observatory for the solar and heliospheric community, potential of national and international community participation through science proposals with Aditya-L1 will be explained. In synergy with other international observatories, both ground- as well as space-experiments, Aditya-L1 would provide data which can address the solar and heliophysics observational aspects. With the Aditya-L1 science data made available to the community, we encourage all to utilize the same for the advancement of understanding the science of space weather.<br></div><div><br></div><div><img src="cid:ii_mal0zp4c0" alt="ISWI Seminar Series.jpg" width="492" height="492"><br></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>-------------------------------------------</div><div><div><font face="times new roman, serif"><b>Dra.
