Physical parameters of near-earth asteroid 1982 DV

An account is given of visual and infrared observations made of Amor asteroid 1982 DV during its discovery apparition. Broadband visual and near-infrared photometry shows it to be an S-class asteroid. Narrowband spectrophotometry shows an absorption feature due to olivine or pyroxene or both centered at 0.93 micrometer. The asteroid is either one of the most reflective S-class asteroids known, or a significant amount of bare rock is exposed on the asteroid's surface. For the nonrotating model considered, ellipsoidal dimensions are 3.5 x 1.4 x 1.4 km.
