Aditya -L1 -Satus and plans for coordinated observations

Overall goal:
Aditya-L1 mission is India's first dedicated scientific mission to study the sun will be inserted in a halo orbit around the L1, which is 1.5 million km from the Earth. The satellite will carry seven payloads, which needs coordinated observations amongst the different payloads and other ground and space observatories. The project is approved and the satellite will be launched around 2020 timeframe by PSLV-XL from Sriharikota. These studies will enhance our current understanding of the Solar Corona and also provide vital data for space weather studies. The complete list of payloads are given below along with main scientific objectives and primary institution responsible for the delivery of the payload.

Visible Emission Line Coronagraph (VELC): To study the diagnostic parameters of solar corona and dynamics and origin of Coronal Mass Ejections (3 visible and 1 Infra-Red channels); magnetic field measurement of solar corona down to tens of Gauss – Indian Institute of Astrophysics (IIA)
Solar Ultraviolet Imaging Telescope (SUIT): To image the spatially resolved Solar Photosphere and Chromosphere in near Ultraviolet (200-400 nm) and measure solar irradiance variations - Inter-University Centre for Astronomy & Astrophysics (IUCAA)
Aditya Solar wind Particle Experiment (ASPEX) : To study the variation of solar wind properties as well as its distribution and spectral characteristics – Physical Research Laboratory (PRL)
Plasma Analyser Package for Aditya (PAPA) : To understand the composition of solar wind and its energy distribution – Space Physics Laboratory (SPL), VSSC
Solar Low Energy X-ray Spectrometer (SoLEXS) : To monitor the X-ray flares for studying the heating mechanism of the solar corona – ISRO Satellite Centre (ISAC)
High Energy L1 Orbiting X-ray Spectrometer (HEL1OS): To observe the dynamic events in the solar corona and provide an estimate of the energy used to accelerate the particles during the eruptive events - ISRO Satellite Centre (ISAC) and Udaipur Solar Observatory (USO), PRL
Magnetometer: To measure the magnitude and nature of the Interplanetary Magnetic Field – Laboratory for Electro-optic Systems (LEOS) and ISAC.

In this workshop we would like to highlight the main objectives of the different payloads and its operational plans. The coordinated observing plan, data telemetry restrictions and data policy will be discussed with the participants.
