It was discovered on 12 June 1936, by English-born South-African astronomer Cyril Jackson at Union Observatory in Johannesburg, South Africa. The asteroid was named after the historical Algoa Bay. Orbit and classification Algoa orbits the Sun in the inner main-belt at a distance of 2.3–2.6 AU once every 3 years and 10 months (1,391 days). Its orbit has an eccentricity of 0.08 and an inclination of 3° with respect to the ecliptic. Prior to its discovery observation in 1936, Algoa was identified as 1929 TT and 1933 UY 1 at Lowell Observatory and Uccle Observatory, respectively. These observations, however, remained unused to extend the body's observation arc. Physical characteristics In 2012, two rotational lightcurves of Algoa were obtained at the U.S. Etscorn Observatory, New Mexico, and at the Riverland Dingo Observatory, Australia. They gave a well-defined, concurring rotation period of 2.768 hours with a brightness variation of 0.20 and 0.21 magnitude, respectively (U=3-/3). The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony S-type asteroids of 0.20, and calculates a diameter of 14.2 kilometers with an absolute magnitude of 11.6. Naming This minor planet was named after the historical Algoa Bay, located approximately 700 kilometers east of the Cape of Good Hope, South Africa. The official 1394 naming citation was published by the Minor Planet Center in April 1953 (M.P.C. 909). References 2016-11-11 last obs.
