  Based on the photographic and the CCD observations of the relative motion of
A, B components of the binary system ADS~9346 obtained with the 26-inch
refractor of the Pulkovo Observatory during 1979-2019, we discover an invisible
companion associated with the A-star. Comparison of the ephemerides with the
positional and the spectroscopic observations allowed us to calculate the
preliminary orbit of the photocenter ($P=15$ years). The minimal mass of the
companion is approximately $0.13~M_\odot$. The existence of the invisible
low-mass companion is implied by the IR-excess based on the IRAS data. To
confirm this, additional observations of the radial velocity near the
periastron need to be carried out.
