13367 Jiří           Discovered 1998 Oct. 18 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Jiří Borovička (b. 1964), of the Astronomical Institute of the Academy of Sciences of the Czech Republic, is known for his work in meteor physics and astronomy, particularly in meteor spectroscopy. He discovered the low- and high-temperature components of meteor radiation. The name was suggested by Z. Ceplecha.
