This Apollo object has an estimated diameter of about 2 km. It shows a spectrum (Fig. 2) different from all the other near-Earth objects here presented. It is redder than the solar spectrum and resembles that of the more primitive C-type asteroids. Its reflectance slope is 3.7 [FORMULA] 0.1 %/103 Å in the spectral range 5000 [FORMULA] 7500 Å, which is consistent with the reflectance slopes of C-type objects more than with those of D-types (lower limit of the reflectance slopes of D objects is about 7%/103 Å).
