Spectrum of 176P/LINEAR obtained with the NOT telescope binned to a resolution of 30 Å, compared with the mean spectrum of 133P/Elst-Pizarro also binned to the same resolution. Spectra are normalized to unity at 5500 Å and shifted vertically by 0.3 for clarity. The spectrum of 176P is plotted only in the 4000 − 7200 Å range as the SNR outside this spectral region is very low. Notice that the spectra of 133P and 176P are similar, both show the slightly and rare negative (blue) slope in this wavelength region, typical of B-type asteroid.
