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