  We have studied finite temperature complex static quark-antiquark potentials
for 2+1 flavor QCD using highly improved staggered action with physical strange
quark masses and light quark masses corresponding to a pion mass of 161 MeV. We
calculated the potential using Wilson line correlators fixed in Coulomb gauge.
For the extraction, we have used HTL motivated parametrization of the
correlators. We found that the real part of the potential is screened above the
crossover temperature and it's close to singlet free energies, whereas the
imaginary part is increasing with both distance and temperature.
