27706 Strogen           Discovered 1985 Oct. 11 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
James A. Strogen (b. 1947) assisted in organizing the Palomar Observatory's 1.2-m Schmidt Oschin Telescope plate archive. In addition to working as a telescope operator at the Mt. Wilson Observatory, he is active in astronomy outreach through his leadership role in the Los Angeles Astronomical Society.
