4853 Marielukac           Discovered 1979 June 28 by C. Torres at Cerro El Roble.
A staff member of the U.S. Nautical Office since 1971, Marie R. Lukac (b. 1947) has played a major role in the continuing integrity of the data in The Astronomical Almanac (notably the list of observatories), The Air Almanac and The Nautical Almanac. This minor planet is named on the occasion of her retirement.
