2384 Schulhof, provisional designation 1943 EC1, is a stony Eunomia asteroid from the middle region of the asteroid belt, approximately 12 kilometers in diameter. It was discovered on 2 March 1943, by French astronomer Marguerite Laugier at Nice Observatory in southeastern France.
The asteroid is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun 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. As the first identification at Heidelberg Observatory from 1909 is not used, the asteroid's observation arc begins with its discovery in 1943.
In April 2002, a rotational light-curve was obtained from photometeric 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 in magnitude (U=3).
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 11.5 and 11.7 kilometers in diameter and its surface has an albedo of 0.27 and 0.28, respectively, while 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.
