If you want to follow up these asteroids recently discovered at Campo Catino Obs., you can use this page for updated ephemeris.
Thank you very much!.

Other observers also have their own follow-up pages, check out this list of links.

Astrometric observations of any of the following objects should be sent directlyto Updated orbits will be available automatically through this page.

By default, ephemerides are geocentric, begin now and are for 20 days at 1day intervals. The desired start date for the ephemeris should be entered inYYYY MM DD format, e.g., 1998 July 19 = 1998 07 19. Note that these ephemerides are intended to assist current observations only.

Start date for ephemerides: Number of dates to o utput

Ephemeris interval: Ephemeris units: days hours

If you select MPC format the elements will be displayed with the ephemerides.If you select any format other than MPC format only the elements are returned.In such cases your browser should download the elements file and save into your local disk.

Supplementary Information

The summary lists the current J2000.0 coordinates, visual magnitude and solar elongation of the selected minor planets, as well as information on the date of last observation (where available), forthcoming opposition data and details on the latest published orbit. The opposition data lists the date of the next opposition and the declination and visual magnitude at that time.

The list of available formats for the orbital elements was correct at the time this document was prepared. It is possible that the Minor Planet Center now supports futher formats. If you select the summary option, any newly supported formats will be listed.

The elements supplied are the latest published elements for the specified objects. Elements will be found even if the designation you enter is a non-principal designation in an identification or if the objct has been numbered.

Ephemerides can be supplied for objects with only Väisälä elements, but the elements themselves are not supplied.

The ephemerides supplied are unperturbed. Ephemerides from perturbed orbit solutions are generated from elements at the nearest 200-day epoch. The accuracy of the ephemerides for most objects will be entirely sufficient to locate the objects for current astrometric observation. Objects must be identified in images by their motion, not by their apparent closeness to a predicted position.

The time-scale of the supplied ephemerides is strictly TT (Terrestrial Time). For practical purposes the difference between TT and UT (Universal Time), currently a little over 1 minute, may be ignored.

If you desire a topocentric ephemeris, enter your observatory code in the appropriate box. As an aide-mémoire, the packed form of the object's designation (as used on the astrometric observation record) is displayed immediately above the ephemeris.
