2384 Schulhof, provisional designation 1943 EC1, is an asteroid and namesake of a small asteroid family in the Eunomian region of the intermediate asteroid belt, approximately 12 kilometers (7.5 miles) in diameter. It was discovered on 2 March 1943, by French astronomer Marguerite Laugier at Nice Observatory in southeastern France. The asteroid was later named after Hungarian astronomer Lipót Schulhof.
Orbit and classification
Schulhof is the principal body and namesake of the Schulhof family, a small asteroid family within the region of the Eunomia family of the main-belt. It orbits the Sun in the central asteroid belt at a distance of 2.3–2.9 AU once every 4 years and 3 months (1,541 days). Its orbit has an eccentricity of 0.12 and an inclination of 14° with respect to the ecliptic.
This minor planet was named in memory of Austrian–Hungarian astronomer Lipót Schulhof (1847–1921), observer of asteroids and comets, discoverer of the main-belt asteroid 147 Protogeneia, and awardee of the Lalande Prize. The official naming citation was published by the Minor Planet Center on 17 February 1984, based on a suggestion by Brian G. Marsden (M.P.C. 8541).
In April 2002, a rotational lightcurve of Schulhof was obtained from photometric observations at the U.S. Oakley Observatory. It gave a well-defined rotation period of 3.294±0.006 hours with a brightness variation of 0.43 magnitude (U=3).
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Schulhof measures 11.5 and 11.7 kilometers in diameter and its surface has an albedo of 0.27 and 0.28, respectively. The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived form 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 12.7 kilometers with an absolute magnitude of 11.8.
