New Object Ephemeris Generator

Use the form below to generate ephemerides for your new objects priorto the assignment of official provisional designations.You enter at least two observations (in thenormalMPC format) for each object into the form below. The observationsof each object can be on the same night. Up to 100 observations may beentered on this form. Then selectGenerate ephemerides toobtain the ephemerides.

Observations that are notformatted correctly will be rejected. Ensure that there is a CarriageReturn at the end of the last observation.

Enter observations below (a guide is included to allow manualentry of the data on those platforms that do not allow cut-and-pasteoperations):

NNNNNPPPPPPPANNYYYY MM DD.ddddd HH MM SS.dd sDD MM SS.d          MM.M B      OOO

By default, ephemerides are geocentric, begin "now" and are for 7 days at 1day intervals. The desired start date for the ephemeris should be entered inYYYY MM DD format, e.g., 2011 June 7 = 2011 06 07. Note that theseephemerides are intended to assist current observations only.

Observatory code:

Start date for ephemerides:

Number of ephemeris positions to output

Ephemeris interval: Ephemeris units: days hours

Display ephemeris positions in: truncated sexagesimal or full sexagesimal or decimal units

Display motions as: "/sec, "/min, "/hr or °/day.

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