Abstract
We report on a preliminary study of static quark anti-quark potential at non-zero temperature in $2+1$ flavor QCD using
$96^3\times N_{\tau}$ lattices with lattice spacing $a=0.028$fm, physical
strange quark mass and light quark masses corresponding to pion mass of about $300$ MeV. We use $N_\tau=32,~24,~20$ and $16$
that correspond to temperature range $T=220-441$ MeV.
The in order to obtain the potential we calculate the Wilson line correlator in Coulomb gauge with additional HYP
smearing to reduce the noise at large quark anti-quark separations.
We apply $0$, $5$ and $10$ steps of HYP smearing to ensure that there is no physical effect from over-smearing.
At the two highest temperatures we also consider a noise reduction technique that is based on an interpolation in the spatial separation between
the static quark and anti-quark.
