15466 Barlow           Discovered 1999 Jan. 14 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Nadine G. Barlow (b. 1958), a planetary geoscientist at Northern Arizona University, studies planetary surface feature geology. The crater designation system she established in her Catalog of Large Martian Impact Craters has been adopted as the international standard for Martian crater data analysis.
