2697 Albina, provisional designation 1969 TC3, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 52 kilometers in diameter. It was discovered on 9 October 1969, by Russian female astronomer Bella Burnasheva at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula.[9]
The dark C-type body is also classified as a X-type asteroid by the large-scale Pan-STARRS survey.[8] It orbits the Sun at a distance of 3.3–3.8 AU once every 6 years and 9 months (2,456 days). Its orbit is tilted by 4° to the plane of the ecliptic and shows an eccentricity of 0.08.[1] The first used precovery was taken at the Royal Observatory of Belgium in 1936, extending the asteroid's observation arc by 33 years prior to its discovery. However, it was already imaged at Lowell Observatory in 1929.[9]
A rotational light-curve of this asteroid was obtained from photometric observations made at the U.S. Palomar Transient Factory in October 2010. The light-curve gave a rotation period of 16.5871±0.0165 hours with a brightness amplitude of 0.16 in magnitude (U=2),[6] and supersedes a previous period of 9.6 hours from a fragmentary light-curve, obtained by French astronomer Laurent Bernasconi in March 2006 (U=1).[7]
According to the space-based surveys carried out by the Infrared Astronomical Satellite (IRAS) and the Japanese Akari satellite, the asteroid has an albedo of 0.055 and 0.053, with a corresponding diameter of 51.5 and 52.7 kilometers, respectively.[3][4] The Collaborative Asteroid Lightcurve Link derives a lower albedo of 0.039 and a diameter of 51.4 kilometers.[5]
The minor planet was named after Russian astronomer from Moscow, Albina Alekseevna Serova, who is a friend of the discoverer.[2] Naming citation was published on 18 September 1986 (M.P.C. 11156).[10]
