We have performed 75As and 23Na nuclear magnetic resonance (NMR) measurements on a single crystal of NaFe0.9835Co0.0165As and found microscopic coexistence of superconductivity with a two-component spin density wave (SDW). Using 23Na NMR we measured the spatial distribution of local magnetic fields. The SDW was found to be incommensurate with a major component having magnetic moment (∼0.2μB/Fe) and a smaller component with magnetic moment (∼0.02μB/Fe). Spin lattice relaxation experiments reveal that this coexistence occurs at a microscopic level.
