  We have analysed RXTE data of the superluminal source GRS 1915+105 in order
to investigate if, despite its extreme variability, it also exhibits the
canonical source states that characterise other black-hole candidates. The
phenomenology of GRS 1915+105 has been described in terms of three states
(named A, B and C) based on their hardness ratios and position in the
colour-colour diagram. We have investigated the connection between these states
and the canonical behaviour and found that the shape of the power spectral
continuum and the values of the best-fit model parameters to the noise
components in all three states indicate that the source shows properties
similar to the canonical very high state.
