Altenkort L, Eller A, Kaczmarek O, Mazur L, Moore G, Shu H-T. Continuum extrapolation of the gradient-flowed color-magnetic correlator at 1.5Tc​. arXiv:2111.12462. 2021.In a recently published work we employ gradient flow on the lattice to extract the leading contribution of the heavy quark momentum diffusion coefficient in the heavy quark limit from calculations of a well-known two-point function of color-electric field operators. In this article we want to report the progress of calculating the recently derived color-magnetic correlator that encodes a finite mass correction to this transport coefficient. The calculations we present here are based on the same ensemble of quenched gauge configurations at 1.5 Tc1.5\, T_c1.5Tc​ that we previously used for the color-electric correlator
