Hereford Arizona Observatory (HAO), IAU-code G95, is an astronomical observatory,[1][2] owned and operated by amateur astronomer Bruce L. Gary.[3] Observational studies of unusual starlight fluctuations in Tabby's Star (KIC 8462852)[4] and WD 1145+017[5] are recent interests.
The observatory is located in Arizona about 130 km (80 mi) southeast of Tucson and about 11 km (7 mi) north of the Mexican border. Coordinates are at the following: North Latitude +31:27:08 and West Longitude 110:14:16, at an altitude of 1,423 m (4,670 ft).[1]
HAO#2 lit by a full moon with Venus setting behind mountains at 2,900 m (9,500 ft) altitude.
HAO view of the southern horizon − mountains are at 4.0 deg elevation on the meridian (vertical red line) − star Canopus (declination -52.7 deg) is transiting.
HAO control room − the Celestron-11 telescope is managed by a dedicated computer on the left; the Meade-14 by one on the right.
