We have observed Cerenkov light, well below threshold, in an integrating Cerenkov counter used to determine particle composition of the secondary hadron beam, which is the source of Fermilab narrow-band neutrinos. The phenomenon can be understood in terms of diffraction effects in a finite length counter caused by radiation emitted by particles traversing the counter even when it is evacuated. At zero pressure, the light can be considered as transition radiation produced when particles enter and leave the counter. A standard Cerenkov diffraction formula describes both the normal Cerenkov radiation and the light emitted below Cerenkov threshold.
