  We present the results of observations of complex powerful type II burst
associated with narrow Earth-directed CME, which was ejected at around 11 UT on
31 May 2013. The observations were performed by radio telescope UTR-2, which
operated as local interferometer, providing the possibility of detection of the
spatial parameters of the radio emission source. There are also polarization
data from URAN-2 radio telescope. The CME was detected by two space-born
coronagraphs SOHO/LASCO/C2 and STEREO/COR1-BEHIND, and was absolutely invisible
for STEREO-AHEAD spacecraft. The associated type II burst consisted of two
successive parts of quite different appearance on the dynamic spectrum. The
first burst was narrow in frequency, had cloudy structure and was completely
unpolarized while the second one represented rich herring-bone structure and
exposed high degree of circular polarization. Both parts of the whole event
reveal band splitting and well distinguished harmonic structure. The positions
and sizes of the sources of the type II burst were found using
cross-correlation functions of interferometer bases. The sources of the type II
bursts elements were found to be of about 15 arcmin in size in average, with
the smallest ones reaching as low as 10 arcmin. Corresponding brightness
temperatures were estimated. In most cases these temperatures were between
$10^{11}$ and $10^{12}$ K with maximum value as high as $10^{14}$ K. The
spatial displacement of the source was measured and model independent
velocities of the type II burst sources were determined.
