Observations of 2000 DP 107 in NAOC: rotation period and reflectance spectrum
Abstract
Photometric observations of a Near-Earth-Asteroid (NEA) 2000 DP 107 were made on four successive nights during October 2000, 1.4-4.7 with the 0.6-m/0.9-m Schmidt telescope of National Astronomical Observatories, CAS (NAOC). The derived rotation period of 0.1156 day was consistent with that obtained by Pravec et al. (IAU Circular No. 7504, 2000). In addition, the relative reflectance spectrum of the asteroid covering 0.35- 0.9 μm was obtained with the NAOC 2.16-m telescope adopting a low-resolution grating ( 10 Å/pix) on October 2, 2000, which revealed that 2000 DP 107 is an M-type asteroid.
