  We present the results of the analysis of the SRG/ART-XC observation of the
Supergiant Fast X-ray Transient IGR J16195-4545 performed on March 3, 2021. Six
bright flares are present in the light curve, with no significant change in
hardness occuring during these flares. The spectrum is described with an
absorbed power law model with a high energy exponential cutoff showing heavy
absorption, with $N_H=(12\pm2)\times 10^{22}\text{ cm}^{-2}$ and
$\Gamma=0.56\pm 0.15$, $E_{cut}=13\pm 2$ keV. Adopting the Bayesian block
decomposition of the light curve, we measured the properties of the observed
flares (duration, rise time, waiting time, released energy and pre-flare
luminosity), which are consistent with the quasi-spherical subsonic accretion
model. The stellar wind velocity of the supergiant is estimated to be $v_{w}
\approx 500$ km s$^{-1}$. Additionally, the system was found to have an unusual
near-IR variability.
