We have searched for magnetic signatures in the B2IV star V 2052 Oph, a β Cep star with stellar wind behavior typical for an oblique magnetic rotator, as β Cep itself. From UV spectroscopy we determined an accurate rotational period and v sin i and present the magnetic measurements as a function of rotational phase. The (small) class of magnetic pulsating early B stars are of great asteroseismological interest.
