Spectroscopic Evidence for Appearance of a New Decretion Disk Around IGR J06074+2205

We report about new episode of decretion disk formation in the IGR J06074+2205 system. Obtained spectral data gives us opportunity to measure peak separation in double-peaked H\alpha\ line as 408+/-55 km/s and hence obtain disk radii as 1.6 star radii. All these facts may says about possible X-ray activity of IGR J06074+2205 in the nearest future.
