F. Shelly, for the Lincoln Near-Earth Asteroid Research project, reported, in connection with the discovery on 2000 April 7 of a fast-moving 18th mag object, that Lisa Brown-Manguso noticed that the object showed clear cometary activity. Subsequent observations confirmed that it was a periodic comet, with a perihelion distance of 1.003 AU and perihelion on 2000 March 9. The comet passed only 0.10 AU from Earth in late 2000 February and early March, when it could have reached 14th mag, but was at high southern declination and is intrinsically very faint. The comet was moved into its present orbit in February 1987 when an encounter to within 0.15 AU of Jupiter made significant changes to the elements. It will make a close approach to the Earth in 2016, passing 0.036 AU from us on March 21. Whilst it could reach 10th magnitude, the pass will be best seen from the Southern Hemisphere. The comet could potentially have an associated meteor shower. This would be maximum around March 30 and the meteors would appear to radiate from 5h 08m -16.
