Prof. Bhupendra Nath Bharagava obtained his M.Sc. degree from Allahabad University and got his M.S. from Ohio State University, USA. After his M.S., Prof. Bharagava joined as a Meteorologist at the Astrophysical Observatory of Indian Meteorological Department in Kodaikanal. Prof. Bharagava was actively engaged in research dealing with magnetosphere and ionosphere. He was instrumental in generating ionograms and magnetograms that can provide reliable and uninterrupted data. The archives of Kodaikanal ionograms are still considered a rich treasure by the global research community as it still provides useful data pertaining to the equatorial region.
He became the Director of Colaba and Alibag Observatories, Mumbai in 1966. During his tenure, the Colaba and Alibag Observatories were reconstituted as Indian Institute of Geomagnetism in 1971 and functioning as an autonomous research institute under Department of Science & Technology, Govt. of India. At IIG, he streamlined the research into observatory and data analysis, solid earth geophysics, upper atmospheric research, and instrumentation. Scientific research activities too were organized into data analysis, experimental and field work, theoretical studies, design and fabrication of instruments, and their maintenance. IIG became a premier centre of excellence for geomagnetic research in the country. Prof. Bharagava's own contribution to the understanding of quasiperiodic oscillations in the geomagnetic field was globally recognized. His team also extensively looked at the interaction between solar wind and geomagnetic changes.
Prof. Bharagava was also instrumental in getting recognition for the Institute as a postgraduate research centre under Bombay University (now Mumbai University). It was under his directorship, four new observatories at Ujjain, Jaipur, Shillong, and Gulmarg became operational. During his tenure, cooperative scientific research was significantly enhanced with (the then) USSR, Australia, USA, and others.
He was elected a fellow of the Indian Academy of Sciences, Bangalore.
