Looking for the weak members of the C$_{60}^+$ family in the
  interstellar medium
  We demonstrate, using the high resolution spectra from the ESPADONS
spectrograph, fed with the 3.6m CFH telescope, that the strength ratios of the
strong--to--weak spectral features, attributed to C$_{60}^+$, are variable. We
found that in the range of expected 9366~\AA\ C$_{60}^+$ feature there are two
diffuse bands centered at 9362.0$\pm$0.1 and 9365.3$\pm$0.1 \AA\ with variable
intensity ratio. We confidently confirm the lack of 9428~\AA\ feature which, in
the laboratory spectra of C$_{60}^+$, is stronger than 9366~\AA. The weakest
laboratory feature, near 9348.4~\AA\, remains below the level of detection in
all spectra. The intensity ratio 9577/9365 is variable. These facts contradict
to their common origin and so -- the identification of some interstellar
spectral features as being carried by the cation of the "soccer ball". We also
refined the rest wavelength position of the strongest diffuse band in this
range: it is 9576.8$\pm$0.1~\AA.
