1996 JA 1 , 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 JA 1 traveled through the usual ecliptic survey region at a rate of 5° hr −1 , and would likely have escaped detection even at V = 11. Rapid astrometry and communication through the Minor Planet Center and the World Wide Web facilitated follow-up observations that indicate 1996 JA 1 has 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 JA 1 shares the same source as the HED meteorites. |
