About this observatory

In the high desert of southern Arizona, about 130 km southeast of Tucson and just 11 km north of the Mexican border, Hereford Arizona Observatory has produced serious research despite being owned and run by a single amateur astronomer.

About Hereford Arizona Observatory

Known by its IAU code, G95, the observatory is owned and operated by amateur astronomer Bruce L. Gary. It consists of two separate installations, HAO#1 and HAO#2, each housing its own telescope.

Telescopes & research

HAO#1 contains an 11-inch Celestron CPC 1100 Schmidt-Cassegrain telescope on an equatorial mount, while HAO#2 houses a 16-inch Astro-Tech Ritchey-Chrétien telescope, also on an equatorial mount. Recent research at the site has focused on unusual starlight fluctuations in Tabby's Star (KIC 8462852) and in WD 1145+017, two of the more puzzling objects in modern astronomy.

Location & getting there

The observatory sits in Arizona at an elevation of 1,423 metres, in a stretch of desert close to the U.S.-Mexico border, coordinates that place it firmly on the map for professional and amateur astronomers tracking its published data.

Visiting Hereford Arizona Observatory

As a privately owned amateur facility, HAO is not set up as a general public visitor site. Anyone interested in its work should check its official website for current information before making contact.
