It was discovered on 28 December 1940, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland. It is named for the municipality of Punkaharju. Orbit Punkaharju is a member of the Postrema family (541), a mid-sized central asteroid family of little more than 100 members.23 The S-type asteroid orbits the Sun at a distance of 2.1–3.5 AU once every 4 years and 8 months (1,698 days). Its orbit has an eccentricity of 0.26 and an inclination of 16° with respect to the ecliptic. Punkaharju was first identified as 1930 QB at Uccle Observatory in 1930, extending the body's observation arc by 10 years prior to its official discovery observation. Rotation period Between 2000 and 2011, several rotational lightcurves of Punkaharju were obtained from photometric observations by astronomers Brian Warner and Pierre Antonini. They gave a well-defined rotation period of 5.01 hours with a brightness variation between 0.26 and 0.43 magnitude (U=3/3/3). In addition, a concurring period of 5.01327 hours was published in 2016, using the Uppsala Asteroid Photometric Catalogue as the main-data source. French CCD-specialist Cyril Cavadore also derived a less secure period of 5.028 hours from his observations in October 2005 (U=2-). Diameter and albedo According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 28.01 and 31.21 kilometers in diameter, and its surface has an albedo between 0.165 and 0.271. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.196 and a diameter of 31.41 kilometers using an absolute magnitude of 9.9. Naming This minor planet is named for the former municipality of Punkaharju, an isthmus region in southeastern Finland (also see Karelian Isthmus). The official 1659 naming citation was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3933). References 2017-05-01 last obs.
