4. Conclusions

The new previously unidentified shell supernova remnant G16.2-2.7 has been discovered in the First Galactic quadrant.

The radio map at 1.4 GHz from NVSS maps has been plotted and the SNR has been clearly shown to be a barrel-shaped or bilateral SNR with the axis of symmetry aligned closely with the Galactic plane.

Angular diameter of 17´ of a circular shell has been fitted to peaks of brightness on its limb. Using a simple model of a spherical hollow shell, a outer diameter and width R= are well fitted to the NVSS and the Effelsberg survey data.

The spectrum based RATAN-600 and Effelsberg surveys at cm wavelengths is fitted by a power law with a spectral index .

The polarization data from the NVSS show that the bright arcs of the SNR are linearly polarized to 6-20 %, indicating a synchrotron radiation and an ordered magnetic field in the shell.
