Abstract
We present time-series optical spectroscopic observations of 3200 Phaethon during its 2007 return, complemented with R-band photometry. The spectral gradient centered around 0.55 μm varies between −5.0 %/0.1 μm and 0.6 %/0.1μm, indicating a B- or C-type color. Moreover, rotational modulation of the spectral slope of this asteroid suggests its surface compositional inhomogeneity, particularly the existence of a C-type surface at a certain longitude on this asteroid.
