Title: *Aditya-L1: A Solar and Heliospheric Observatory from India*
Speaker: Dr. K. Sankarasubramanian
Indian Space Research Organisation (ISRO)

Abstract:
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,
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.
