  Optical spectroscopy study of the recent AG Peg outburst observed during the
second half of 2015 is presented. Considerable variations of the intensity and
the shape of the spectral features as well as the changes of the hot component
parameters, caused by the outburst, are discussed and certain similarities
between the outburst of AG Peg and the outburst of a classical symbiotic stars
are shown. It seems that after the end of the symbiotic nova phase, AG Peg
became a member of the classical symbiotic stars group.
