Hereford Arizona Observatory, Astronomical observatory in Hereford, Arizona.
Hereford Arizona Observatory is a private astronomical facility in rural Arizona with two separate domes housing specialized telescopes. The site contains an 11-inch Schmidt-Cassegrain telescope alongside a larger 16-inch Ritchey-Chrétien instrument, both equipped with computerized control systems for detailed sky observations.
The facility was founded by amateur astronomer Bruce L. Gary and received the International Astronomical Union designation G95. Over time it became known for systematic observations of variable stars and unusual stellar phenomena across multiple seasons.
Scientists and astronomers at the facility contribute to the understanding of exoplanets through detailed photometric measurements and documentation of stellar phenomena.
The facility sits at elevation in a remote desert location southeast of Tucson, offering clear skies for nighttime observations. Since it is a working research installation rather than a public venue, access and viewing opportunities may require prior arrangement.
The observatory gained recognition through monitoring Tabby's Star, a mysterious object with unusual brightness fluctuations that puzzle astronomers. Long-term photometric tracking at this site contributes valuable data to understanding such puzzling stellar activity.
