Description
Summary:	1996 JA1, which approached to 0.003 AU of the Earth on 1996 May 19.7 UT, was discovered on films exposed 5 days earlier during the course of the high-ecliptic-latitude Bigelow Sky Survey. The utility of high-latitude surveying for near-Earth objects is demonstrated by the fact that 1996 JA1traveled through the usual ecliptic survey region at a rate of 5° hr−1, and would likely have escaped detection even atV= 11. Rapid astrometry and communication through the Minor Planet Center and the World Wide Web facilitated follow-up observations that indicate 1996 JA1has a mean diameter of 170 m, a rotational period of 5.23 hr, and an albedo of 0.30. With a spectrum consistent with the V class, it is possible that 1996 JA1shares the same source as the HED meteorites.
