    Select object(s) from the current list of objects needing confirmation (NEO desirability score, discovery date, rough current position and magnitude given, as well as number of observations, arc, nominal H and number of days since it was last observed). Objects flagged with an "S" in the Note column are possibly in geocentric orbit and might soon be removed.

    All objects with V = to , with Decl. between ° and °, with an NEO desirability score of % to %

    or just the objects selected below:

    The information in the table (including any PCCP objects) is available in a text file. The layout of this file matches the table layout exactly, except that the R.A. is converted to decimal hours and the Decl. to decimal degrees.


    Select your viewing point:

    Geocentric Observatory code

    Longitude ° E, latitude °, altitude m.

    Longitudes and latitudes should be entered in decimal degrees.

    Start ephemerides at now + hours

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

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

    If you need to delete one of your discoveries as "does not exist" or "artificial", or flag it as "cometary", etc., please submit the corresponding "action code" through our Submit Action Code Form


    Notes on how to begin your own astrometric program are available.

    Please ensure that you have read the additional notes on the NEOCP.

    Please do not report observations of non-NEOCP objects in the same message as observations of objects on this page!

    Get NEO Ratings to see whether you should report a possible NEO.

    Please report unsuccessful attempts to detect objects listed here that are NOT listed as `updated' or that have not been updated in the past 24 hours using the NEOCP Blog.

    Please note that observations and orbits of objects accessible via this service are made available only for your personal use. They are not to be promulgated via any medium. The data are preliminary until they appear on an MPEC or MPS.

    It is possible that some of the objects listed here are comets, either recognised or currently unrecognised as such. All reports of new cometary activity should be made using the following web form (Reports of activity for known comets made to the above web form will be ignored.)
    New reports of cometary activity must be made using this web form in order to be considered for inclusion in any resulting MPEC announcing cometary status. We do not flag suspected comets on this page because we do not wish to influence observers.

    You can now access ephemerides for the variant orbits used in the uncertainty plots from the pages listing the offsets from the nominal solutions.

    Please read (or here) about the coloration used in the uncertainty plots.

    You are reminded that a cross-reference of designations that have appeared here previously is available elsewhere.

    If none of these objects are within the capabilities of your system, check out the Dates of Last Observation of NEOs not seen recently (in R.A. order), the list of bright recovery opportunities, or the Spaceguard Central Node's Priority List for alternate useful targets.
