A test of comet and meteor shower associations

A reevaluation of the comet/meteor shower and shower/shower associations suggested by Cook (1973, in Evolutionary and Physical Properties of Meteoroids, U.S. Govt. Printing Office, Washington, D.C., NASA SP-319) is made using two orbital discriminant techniques. Twenty-six of his pairings are confirmed, five are rejected, and one new match is found; Comet Ikeya (1964 VIII) is asserted to be the source of the ? Geminids, bringing to sixteen the number of comets which produce meteor showers in Cook's list. No known asteroid shows a convincing relationship to any of the showers.
