Scientific paper

The paper presents photometric and spectroscopic observations of SN 1986 G, spanning up to one year after the explosion. Although the overall spectral evolution of the object is typical of SN Ia, some peculiarities are noted. The expansion velocities of the envelope at different phases, deduced from the Si II 6355 A doublet, are among the slowest ever detected. The strong broad emission at about 4100 A, usually present in the SN Ia near-maximum spectra, is missing.
