6886 Grote           Discovered 1942 Feb. 11 by L. Oterma at Turku.
Named in honor of Grote Reber (b. 1911), pioneer radioastronomer. A radio engineer by profession, he became intrigued by Jansky's 1932 detection of radio waves of extraterrestrial origin. From a series of homemade radio receivers and a 9.4-m parabolic dish antenna in his backyard in Wheaton, Illinois, Reber obtained the first detailed quantitative maps of the radio sky and published these in a series of papers during the 1940s. His stunning results gradually opened the consciousness of others to this very powerful method of observing the universe. Name suggested and citation prepared by G. C. L. Aikman.
