Lower superconducting critical fields $H_{rm c1}$ of UTe have been determined. Orthorhombic UTe has magnetic easy axis along the -axis. We found $H_{rm c1}$ perpendicular to showed anomalous enhancement. By comparing with anisotropy of upper critical fields, effect of magnetic fluctuations on superconductivity is suggested.
