The primary work at the various observatories is to determine basic parameters about minor planets.  This work is done on an individual basis, in collaboration with another amateur or professional astronomer, or as part of a group project.  The data presented here is copyrighted by Robert D. Stephens.  It has been or will be published in the Minor Planet Bulletin or other publications.  If you wish to use the data for your own analysis, please contact me and be sure to give proper credit.  Thank you. 

 

In most cases, the underlying data can be found at the Asteroid Data Upload (ADU) site maintained here at the Minor Planet Observer.  Exceptions include data embargoed for future publication.
