 Two weak diffuse interstellar bands at 963.2 and 957.7 nm were detected in absoption toward several reddened stars. The were assigned to C<sub>60</sub><sup>+</sup> on the basis of laboratory electronic spectra of the molecular catio isolated in neon matrix. These features were blue-shifted less than 0.1 % from the strongest matrix bands. Even though the level of agreement is in the normal range, the identification was not beyond doubt. Two weak diffuse interstellar bands at 963.2 and 957.7 nm were detected in absoption toward several reddened stars.

This detection dispels any possibly remaining doubt on the detection of this molecular cation. In fact, the authors detected the two weaker features toward the stars HD 183143 and HD 169454, the latter from archival data.
