    The following list of follow-up sites have been prepared by observers using the Minor Planet Ephemeris Service in the hope that other observers will perform follow-up astrometry on their discoveries.

    Notes on beginning your own astrometric observation program are available.

    In addition, links are provided to the following external services for observers: Note that the Minor Planet Center cannot endorse use of any external services.
