We present new near- and mid-infrared photometry of the infrared source near HV Tau that was proposed as a Herbig-Haro object by Magazzù & Martin (1994). We draw a different conclusion, namely that this object is a T Tauri star with strong forbidden emission lines as had been suggested originally. The presence of a Herbig-Haro flow in the vicinity of a weak-lined T Tauri star like HV Tau would have imposed a problem on models of T Tauri stars and their environment. With the reinstatement of the companion to HV Tau as a T Tauri star this problem disappears.
