1394 Algoa, provisional designation1936 LK, is a stonyasteroid from the inner regions of theasteroid belt, approximately 14 kilometers in diameter. It was discovered on 12 June 1936, by English-born South-African astronomerCyril Jackson atUnion Observatory in Johannesburg, South Africa.[7] The asteroid was named after the historicalAlgoa Bay.[2]
Algoa orbits the Sun in theinner main-belt at a distance of 2.3–2.6 AU once every 3 years and 10 months (1,391 days). Its orbit has aneccentricity of 0.08 and aninclination of 3° with respect to theecliptic.[1] Prior to its discovery observation in 1936,Algoa was identified as1929 TT and1933 UY1 atLowell Observatory andUccle Observatory, respectively. These observations, however, remained unused to extend the body'sobservation arc.[7]
In 2012, two rotationallightcurves ofAlgoa were obtained at the U.S. Etscorn Observatory, New Mexico, and at the Riverland Dingo Observatory, Australia. They gave a well-defined, concurringrotation period of 2.768 hours with a brightness variation of 0.20 and 0.21magnitude, respectively (U=3-/3).[4][5] TheCollaborative Asteroid Lightcurve Link assumes a standard albedo for stonyS-type asteroids of 0.20, and calculates a diameter of 14.2 kilometers with anabsolute magnitude of 11.6.[3]
Thisminor planet was named after the historicalAlgoa Bay, located approximately 700 kilometers east of theCape of Good Hope, South Africa.[2] The officialnaming citation was published by theMinor Planet Center in April 1953 (M.P.C. 909).[8]
