The Aditya-L1 Mission marks a major milestone in India’s space science programme, enabling continuous and comprehensive observations of the Sun from the Sun–Earth L1 point. Scientific data from the mission are regularly released in public domain for global scientific utilization. At present there are more than 23 TB data in public domain and several important scientific results have been published in International peer reviewed journals. To further maximize the scientific return from this unique mission, the Indian Space Research Organisation (ISRO) has released the first Announcement of Opportunity (AO) inviting proposals from the Indian solar physics community for Aditya-L1 observation time. The below document outlines the eligibility criteria, proposal submission process, and observation schedule for proposal submission. Researchers are encouraged to go through the complete AO details and submit high-quality proposals that advance our understanding of solar and heliospheric science.
