  The young eruptive star V1647 Ori was observed with MIDI, the mid-infrared
interferometric instrument at the Very Large Telescope Interferometer (VLTI),
on March 2, 2005. We present the first spectrally resolved interferometric
visibility points for this object. Our results show that (1) the mid-infrared
emitting region is extended, having a size of ~ 7 AU at 10 um; (2) no
signatures of a close companion can be seen; (3) the 8-13 um spectrum exhibits
no obvious spectral features. Comparison with similar observations of Herbig Ae
stars suggests that V1647 Ori probably possesses a disk of moderate flaring. A
simple disk model with T ~ r^{-0.53}, \Sigma ~ r^{-1.5}, M_d = 0.05 M_Sun is
able to fit both the spectral energy distribution and the observed visibility
values simultaneously.
