3743 Pauljaniczek           Discovered 1983 Mar. 10 by E. Barr at the Anderson Mesa Station of the Lowell Observatory.
Paul M. Janiczek (b. 1937), at the U.S. Naval Observatory during 1967--1997 and head of the Astronomical Applications department since 1990, is a specialist in celestial mechanics, ephemerides and navigation. He supervised the U.S. contributions to and production of the Astronomical, Nautical and Air Almanacs.
