A challenge to standard leptonic SSC models are so-called orphan TeV flares, i.e. enhanced very high energy (VHE) gamma-ray emission without any contemporaneous X-ray flaring activity, that have recently been observed in TeV-blazars (e.g., 1ES 1959+650). In order to explain the orphan TeV flare of 1ES 1959+650 observed in June 2002, the co-called hadronic synchrotron mirror model has been developed. Here, relativistic protons are proposed to exist in the jet, and interact with reflected electron-synchrotron radiation of the precursor SSC flare. If the reflector is located in the narrow line region, time shifts of several days are possible between the precursor and the orphan flare. The external photons, blueshifted in the comoving jet frame, are able to excite the Delta(1232)-resonance when interacting with protons of Lorentz factors ~ 103 - 104. The decay products of this resonance include charged pions which, upon decay, give rise to neutrino production during the orphan flare. In this paper we calculate the expected neutrino emission for the June 4, 2002, orphan TeV flare of 1ES 1959+650. We compare our results with the recent observations of AMANDA-II that have been claimed to provide a hint for a neutrino event during the orphan flare of this blazar. We find that the expected neutrino signal from the hadronic synchrotron mirror model is insufficient to explain the claimed neutrino signal from the direction of 1ES 1959+650.
