We performed ultracold neutron storage measurements to search for additional losses due to neutron () to mirror-neutron () oscillations as a function of an applied magnetic field . In the presence of a mirror magnetic field , ultracold neutron losses would be maximal for . We did not observe any indication for oscillations and placed a lower limit on the oscillation time of at 95% C.L. for any between 0 and .
