title = "R- and J-band photometry of Comets 2P/Encke and 9P/Tempel 1",
abstract = "Near-simultaneous R- and J-band photometric measurements of the short-period Comets 2P/Encke and the Deep Impact mission target 9P/ Tempel 1 were obtained. The resulting R-J colors are +0.82 ± 0.08 mag and +1.46 ± 0.13 mag for Encke and Tempel 1, respectively. Tempel 1's color is redder than the solar R-J color index of +0.76. The Tempel 1 observations directly detected the nucleus while the Encke observations likely suffered from coma contamination.",
