In the Letter, "A Planet Orbiting the Star rho Coronae Borealis" by Robert W. Noyes, Saurabh Jha, Sylvain G. Korzennik, Martin Krockenberger, Peter Nisenson, Timothy M. Brown, Edward J. Kennelly, and Scott D. Horner (ApJ, 483, L111 [1997]), a software error caused the sign of the reported radial velocity variations of rho Coronae Borealis to be reversed. This error has no effect on the period, amplitude, or eccentricity of the derived orbit and thus does not affect the main conclusion of the paper. However, the longitude omega of periastron reported in Table 1 is off by 180 deg;, and the predicted time of a possible planetary transit Ttransit is off by approximately 1/2 period. The correct values are omega = 30 deg +/- 74 deg and Ttransit = 2,450,657.88 +/- 0.54 HJD.
