The central spin model is important for developing qubits as sensors of environmental noise and protecting qubits from decoherence. In both noise spectroscopy and dynamical decoupling protocols, the central qubit is actively controlled. However, the qubit-bath interaction may enable changes in the qubit state to trigger changes in the bath, ultimately modifying the evolution of the qubit [1]. Here, we experimentally observe the self-interaction of the electron spin of the nitrogen vacancy (NV) center in diamond mediated by a bath of polarized <sup>13</sup>C nuclear spins. We are even able to detect the polarization of the bath using phase-resolved Hahn echo sequences. These techniques may assist in preparing high-fidelity memory states, improving nuclear spin hyperpolarization, and investigating the nature of environmental noise.<br/>[1] Y.-X. Wang and A. A.
