Just to make clear an easy and direct way of getting identifications for suspect asteroids or comets in the fields of variables, the Minor Planet Center has a look-up utility that includes all objects with a reasonably determinate orbit: http://cfaps8.harvard.edu/~cgi/CheckSN.COM Note that the input deate defaults to the time you connect to the page, but can be changed to any date within two years of the present. This list will be more up-to-date than commercial software packages, but for most purposes involving bright asteroids, either approach will work. \Brian
