A Minor-Planet Follow-Up Page

(Updated: June 3, 2011)

This page will generate ephemerides for objects discovered serendipitously during the course of our asteroid shape studies program using the Vatican Advanced Technology Telescope (IAU Code 290). Any follow-up observations or searches of your archives for pre-discovery data is greatly appreciated. For further information, please contact Bill Ryan .

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

Note: Ephemerides that indicate they are based on Väisälä elements are approximations that are most likely only good for a few weeks from discovery (indicated next to designation below) at best.

Astrometric observations of any of the following objects should be sent directly to mpc@cfa.harvard.edu. Updated orbits will be available automatically through this page.

Options:

By default, ephemerides are geocentric, begin now and are for 20 days at 1 day intervals. The desired start date for the ephemeris should be entered in YYYY MM DD format, e.g., 2003 July 19 = 2003 07 19. Note that these ephemerides are intended to assist current observations only.

Start date for ephemerides: Number of dates to output

Ephemeris interval: Ephemeris units: days hours minutes seconds

Observatory code:

Display positions in: truncated sexagesimal orfull sexagesimal ordecimal units

Display motions as: "/sec "/min "/hr °/day

Total motion and direction Separate R.A. and Decl. motions

Suppress output if sun above local horizon

Suppress output if object below local horizon

Generate perturbed ephemerides for unperturbed orbits

Also display elements for epoch

Format for elements output:

none	MPC 1-line	MPC 8-line
SkyMap (SkyMap Software)	Guide (Project Pluto)	xephem (E. Downey)
Home Planet (J. Walker)	MyStars! (Relative Data Products)	TheSky (Software Bisque)
Starry Night (Sienna Software)	Deep Space (D. S. Chandler)	PC-TCS (D. Harvey)

If you select 8-line MPC format the elements will be displayed with the ephemerides. If you select any format other than 8-line MPC format, only the elements are returned. In such cases your browser should download the elements file and save it to your local disk.

If you select 8-line MPC format, you may display the residual block for the objects selected:

Show residuals blocks. Show only residual lines containing observations from code .

Supplementary Information

Summary: 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.
Formats: 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.
Elements: 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 object has been numbered.
Ephemerides: 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. For NEOs with perturbed orbit solutions, the ephemerides are generated from elements at the nearest 2-day (or better) epoch.

This service utilises the Minor Planet Ephemeris Service, courtesy of the IAU's Minor Planet Center. It has been made possible by Process Software Corporation, and their excellent VMS Web server, Purveyor.

The calculations will be performed on the Tamkin Foundation Computing Network.
