The comet, also designated P/2006 M3, was discovered by Edward Emerson Barnard on June 24, 1889, and was re-discovered after 116 years. On July 19, 2006, 177P came within of Earth. From late July through September 2006 it was slightly brighter than expected at 8th magnitude in the constellations Hercules and then Draco. Perihelion was August 28, 2006. It was last observed in December 2006 when it was about from the Sun.
