The reflectance spectra of the eight asteroids, normalized at 1 around 5500 Å, are shown in Fig. 1 to Fig. 3. The objects we observed are: 1 Aten (3753 1986 TO ), 4 Apollo (1864 Daedalus, 5786 Talos, 1989 JA, 2063 Bacchus ), and 3 Amor (3352 McAuliffe, 4954 Eric, 5836 1993 MF ).
For each object an indication of the diameter is given (Tholen, 1995). Some of the spectra show some shallow spurious features which are probably due to the division by the solar analog spectrum, that is a non perfect elimination of the solar features, or also to a non perfect cancellation of the atmospheric O2 bands at 7612 Å and 6880 Å.
