Comet Nishikawa-Takamizawa-Tago (1987c) appears to be an excellent candidate as parent of the Epsilon Geminid meteor shower. A comparison of its orbital parameters and theoretical meteor radiant with the observed characteristics of the Epsilon Geminids, along with the fact that the earth makes its closest approach to the comet's path in October when the shower is seen and a more distant approach in July when no shower has been detected, indicates that 1987c is more likely to be the parent than a previously proposed comet (1964 VIII Ikeya). Comet 1987c has preceded the earth to the closest approach position by 230-240 days, and at that time was 0.016 AU within the earth's orbit: these conditions have previously been shown to be favorable to the production of prominent meteor showers or storms.
