The authors present {mu}{sup +} paramagnetic shift measurements between 12 K and about 65 mK in cerium magnesium nitrate (CMN) to investigate its utility as an in-situ temperature calibration source for low temperature {mu}SR experiments. CMN is a salt which exhibits Curie-law susceptibility to temperatures as low as 5 mK. The {mu}{sup +} Knight shift is measured to be (1.46 {+-} 0.03) {times} 10{sup {minus}3}/T + (0.004 {+-} 0.02) {times} 10{sup {minus}3}, corresponding to a transferred hyperfine field of {minus}28.5 kOe/{mu}{sub B}.
