The asteroids bearing the names related to the Observatory
Mr. Tsutomu Seki, an internationally known comet observer and co-discoverer
of Comet Ikeya-Seki, kindly gave me the opportunity to suggest the names for
some of the minor planets (asteroids) he has discovered at Geisei Observatory,
Kochi, Japan. Subsequently, Minor Planets Stanthorpe, Girraween, Charleville,
Mout Kent, and Arthurpage were born.
