7564 Gokumenon           Discovered 1988 Feb. 7 by R. Rajamohan at Kavalur.
M. G. K. ("Goku") Menon (b. 1928), Vikram Sarabhai Distinguished professor of the Indian Space Research Organization, is renowned for his experimental cosmic-ray work at the Tata Institute. He provided strong support for building the 2.3-m telescope at Kavalur and the radioastronomy facility at Ootacamund.
