Named in honor of Tadeusz Michałowski (b. 1954), Polish astronomer at the Astronomical Observatory of Adam Mickiewicz University in Posnan. Michałowski developed a formalism for computing the pole orientation, shape and sidereal rotation period of a minor planet, incorporating both the magnitude and timing information contained in lightcurve observations, in a simultaneous least-squares solution. This method, or methods similar to it, are now widely used standard analysis tools, and they have greatly improved the quality of such determinations. Name suggested by H. Rickman, citation prepared by A. W. Harris.
