We confirm the report by Madejski et al. that the X-ray flux of the newly discovered ROSAT source (RX J1940.1-1025), 37 arc min away from NGC 6814, is periodically modulated at 3.4 hours. This source is in fact responsible for the modulation earlier attributed to the X-ray flux from the Seyfert galaxy NGC 6814. The source was optically identified with a blue emission line object of V≃16mag. The optical spectrum resembles that of a magnetic CV. The X-ray spectrum shows two distinct components: a soft black body component with kT_BB=70eV and a hard power law component with a photon index of 1.1. We suggest that the object is either an AM Her or an intermediate polar (IP). A series of optical spectroscopic observations have established a sinusoidal radial velocity curve from the Hα emission line with a period of 12120±3s (90%) and half amplitude ±165km/s.
