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.
