New Extended Radio Sources From the NVSS
  We report the results of the spectroscopic observations carried out at the
SAO RAS 6-m telescope for the optical components of nine new extended radio
sources found in the NVSS catalog. The measured redshifts of the host galaxies
are in the range of z=0.1-0.4. The physical sizes of radio sources were
calculated within the standard cosmological model. The two most extended
objects, 0003+1512 and 0422+0351 reach the sizes of 2.1 Mpc and 4.0 Mpc,
respectively. This is close to the maximum size of known radio sources.
