  We searched for and detected stellar streams or moving groups in the solar
neighbourhood, using the data provided by the 1st RAVE public data release.
This analysis is based on distances to RAVE stars estimated from a
color-magnitude relation that was calibrated on Hipparcos stars. Our final
sample consists of 7015 stars selected to be within 500 pc of the Sun and to
have distance errors better than 25%. Together with radial velocities from RAVE
and proper motions from various data bases, there are estimates for all 6
phase-space coordinates of the stars in the sample. We characterize the orbits
of these stars through suitable proxies for their angular momentum and
eccentricity, and compare the observed distribution to the expectations from a
smooth distribution. On this basis we identify at least four "phase space
overdensities" of stars on very similar orbits in the Solar neighbourhood. We
estimate the statistical significance of these overdensities by Monte Carlo
simulations. Three of them have been identified previously: the Sirius and
Hercules moving group and a stream found independently in 2006 by Arifyanto and
Fuchs and Helmi et al. In addition, we have found a new stream candidate on a
quite radial orbit, suggesting an origin external to the Milky Way's disk.
Also, there is evidence for the Arcturus stream and the Hyades-Pleiades moving
group in the sample. This analysis, using only a minute fraction of the final
RAVE data set, shows the power of this experiment to probe the phase-space
substructure of stars around the Sun.
