Introduction to Severe Space Weather – Expert Lecture by Dr. Balan Nanan

 

The Department of Physics, University of Kerala, Kariavattom Campus, organized an invited lecture on “Introduction to Severe Space Weather” on 1 June 2026 at the Department Seminar Hall. The session was delivered by Dr. Balan Nanan, Distinguished Professor, Institute for Space-Earth Environmental Research (ISEE), Nagoya University, Japan.

The lecture provided an engaging introduction to the science of space weather and its growing importance in the modern technological era. Dr. Nanan explained the physical processes occurring on the Sun, including solar flares and coronal mass ejections (CMEs), and discussed how these phenomena propagate through interplanetary space to influence the Earth's near-space environment. He highlighted the effects of severe space weather on satellite operations, communication systems, navigation networks, power grids, and other critical technological infrastructures.

Drawing from his extensive experience in space physics research, Dr. Nanan introduced participants to the dynamics of the solar wind, interplanetary magnetic fields, and the mechanisms responsible for geomagnetic disturbances. The session also covered notable historical events such as major geomagnetic storms and emphasized the need for continuous monitoring and forecasting of space weather to mitigate technological risks.

The lecture was attended by faculty members, research scholars, postgraduate students, and undergraduate students from various departments. The interactive session that followed enabled participants to engage with the speaker on topics ranging from solar activity cycles and space weather prediction to contemporary challenges in space science research.

The programme commenced with a welcome address by Dr. Subodh G, who introduced the distinguished speaker and highlighted the significance of interdisciplinary research in space science. The event concluded with a vote of thanks delivered by Dr. Mamata Sahoo, who expressed gratitude to Dr. Balan Nanan for sharing his valuable insights and acknowledged the efforts of all those who contributed to the successful organization of the programme.
