1334 Lundmarka, provisional designation 1934 OB, is a carbonaceous asteroid from the asteroid belt about 30 kilometers in diameter. It was discovered on July 16, 1934 by astronomer Karl Reinmuth at Heidelberg Observatory in Germany.[4]
The assumed C-type asteroid orbits the Sun at a distance of 2.6–3.2 AU once every 5 years (1,816 days). It has a rotation period of 6¼ hours and a derived geometric albedo of 0.15 rather than one of 0.06, as measured by IRAS, the Infrared Astronomical Satellite, back in the 1980s.[1][3]
In September 2014, photometric light-curve observations of nine asteroids, including 1334 Lundmarka, at the Oakley Southern Sky Observatory in Coonabarabran, Australia, measured the asteroid's rotation period to be 6.250±0.003 hours with an amplitude of 0.70 in magnitude.[5]
The asteroid is named after Swedish astronomer Knut Emil Lundmark (1889–1958), who was the head of the Lund Observatory. He extensively studied globular clusters and galaxies, and pioneered in measuring galactic distances and absolute stellar magnitudes. Lundmark also appeared in national radio with programs on popular astronomy and the history of science. The lunar crater Lundmark is also named in his honour.[2]
