8348 Bhattacharyya           Discovered 1988 Jan. 26 by R. Rajamohan at Kavalur.
Jagadish Chandra Bhattacharyya (b. 1930) participated in the discoveries of the atmosphere of Jupiter III (Ganymede) and the rings of Uranus. Also an eminent solar astronomer, he was director of the Indian Institute of Astrophysics in Bangalore and was instrumental in the completion of the 2.3-m telescope at Kavalur.
