Scientific paper

A brief summary of the results obtained by photometric, spectral, spectrophotometric and polarization observations of the Kuwano-Honda peculiar object is presented. The analysis of the results allows the authors to classify the object as an anomalous slow nova of RT Serpentis type. Evidence is found for circumstellar dust formation which may explain the deep minimum in 1980 - 81. The fact, that during the last few years the burst component of this binary system has been in a state corresponding to the Eddington luminosity and that the physical conditions and chemical composition of the outer layers of the component are the same as in the atmospheres of normal supergiants, is of great interest for the theory of nova outbursts and the theory of stellar evolution.
