Recent activity of the symbiotic star AX Per.

Echelle medium high dispersion spectroscopy and UBV photoelectric photometry of the symbiotic star AX Per, carried out in the period November 1989 to March 1990, are presented. Maximum of the star's brightness was observed in December 1989. Deep minimum was observed in all filters during January 7 to March 1990. It was interpreted as the eclipse of the cool component by the hot one. The radius of the red giant (160 R_sun) and the radius of the hot object (105 R_sun) were determined. No high excitation lines were observed. The absorption shell spectrum of once ionized metals (Ti II, V II, Sc II, Cr II) and neutral metals (Fe I, Ti I, Cr I) is presented. The emission line spectrum was characterized by the Fe II, [Fe II], and H I lines. A secondary emission component in the red emission wings of the Fe II and H I lines was observed.
