  We present the analysis of spectroscopic time-series observations of the roAp
star 10 Aql. Observations were carried out in July 2006 with the UVES and SARG
spectrographs simultaneously with the MOST mini-satellite photometry. All these
data were analysed for radial velocity (RV) variations. About 150 lines out of
the 1000 measured reveal clear pulsation signal. Frequency analysis of the
spectroscopic data gives four frequencies. Three highest amplitude frequencies
in spectroscopy coincide with the photometric ones. Phase-amplitude diagrams
created for the lines of different elements/ions show that atmospheric
pulsations may be represented by a superposition of the standing and running
wave components, similar to other roAp stars. The highest RV amplitudes,
300-400 m/s, were measured for Ce II, Dy III, Tb III, and two unidentified
lines at lambda 5471, 5556 A. We discovered ~0.4 period phase jump in the RV
measurements across the Nd III line profiles. It indicates the presence of the
pulsation node in stellar atmosphere. The phase jump occurs at nearly the same
atmospheric layers for the two main frequencies. There is no rotational
modulation in the average spectra for the 6 different nights we analysed.
