The Junk Bond Observatory (JBO; code: 701) is located in the Sonoran Desert at Sierra Vista, Arizona, United States.

It was established by amateur astronomer David Healy in his backyard in 1996,[2] using a Celestron 14 SCT and a 16-inch Meade LX200 telescopes in a roll-off shelter.

The discovery of the remaining 53 numbered minor planets is credited directly to the observatory (see list below).

[1] Until his death in 2011, David Healy was a frequent contributor of follow-up observations to objects on the Minor Planet Center's Near-Earth Object Confirmation Page, surveyed for asteroids netting approximately four new discoveries per month as of January 2007, performed discovery and confirmation photometry of extrasolar planet transits, and performed photometry of cataclysmic variable stars and active galactic nuclei.

The telescope operated robotically, unattended for most of the night, controlled by software by Bob Denny and Jeff Medkeff.
