Bengaluru: Over 200 solar physicists from India and abroad have convened in Bengaluru this week for an international conference on ‘Sun, Space Weather, and Solar-Stellar Connections.’ Organized by the Indian Institute of Astrophysics (IIA), the event marks the 125th anniversary of the Kodaikanal Solar Observatory (KSO), a cornerstone of solar research in India since its establishment in 1899.
The conference, running from January 20–24, celebrates the legacy of KSO, renowned for its rich repository of solar observations and pivotal contributions to the field of solar astrophysics. With themes spanning solar magnetism, space weather, solar-stellar connections, and upcoming solar facilities, the event is a hub for sharing cutting-edge research and fostering international collaborations.
The Kodaikanal Solar Observatory, a historic facility under the IIA, has been instrumental in advancing our understanding of solar phenomena such as sunspots, solar flares, and coronal mass ejections. Its unique location and state-of-the-art equipment have positioned it as a vital resource in global solar research.
Speaking at the conference, DST Secretary Prof. Abhay Karandikar highlighted initiatives like the digitization of KSO’s archival records and its contributions to the Aditya-L1 mission through the Visible Emission Line Coronagraph. He also emphasized the importance of upcoming ventures like the proposed National Large Solar Telescope (NLST) in Ladakh, which promises to open new frontiers in solar astrophysics.
Former ISRO Chairman A.S. Kiran Kumar encouraged the solar physics community to conceptualize innovative instruments that ISRO could launch, reaffirming India’s capabilities in advancing space-based solar research.
The conference has drawn eminent scientists, including Prof. John Leibacher from the USA’s National Solar Observatory, who lauded the KSO as a unique facility contributing to the understanding of the Sun as a system. He also expressed the international solar community’s strong support for the NLST initiative.
IIA Director Prof. Annapurni Subramaniam described the conference as a celebration of solar astronomy’s growth in India and a platform for discussing global advancements. A diverse program of presentations, poster sessions, and discussions has brought together seasoned scientists, early-career researchers, and students.
A special public talk by Prof. Nat Gopalswamy from NASA Goddard Space Flight Center was hosted at CHRIST University on January 23, aimed at inspiring students and the general public to explore the wonders of solar science.
With over 205 participants, including students and international delegates, the conference is strengthening ties between the global scientific community and India’s solar research initiatives. The focus on emerging technologies and facilities like the NLST signifies India’s leadership in solar astrophysics and its commitment to exploring the Sun’s influence on the Earth and beyond.
