Radio-optical identification of very-steep spectrum radio sources from   the UTR-2 catalogue
  We used radio source catalogues accessible from the CATS database (http://cats.sao.ru) to establish radio continuum spectra for decametric radio sources in the UTR-2 catalogue (Braude et al., 1978--1994). From these, we select a sample of 23 sources with ultra steep radio spectra (\alpha<=-1.2, S ~ \nu^{\alpha}) and present accurate positions and sizes from FIRST and NVSS. The search for optical counterparts from the APM (object) and DSS (image) databases, as well as infrared and X-ray identifications of these UTR sources are in progress.
