In 2004, residents of the southern hemisphere had the opportunity to watch the comet gradually brighten as it raced toward perihelion. On May 6, 2004 the comet approached within 0.32 AU of the Earth. Beginning in early May, the comet started racing north and burst into view in the northern hemisphere when it had reached almost maximum brightness.

With a near perihelion orbital eccentricity of 1.00069 (epoch 2004-May-18) that keeps a barycentric epoch 2014-Jan-01 eccentricity of 1.00067, this hyperbolic comet is going to be ejected from the Solar System.
