Abstract	A qualitative discussion is presented on the subject of electromagnetic radiations emanating from an are discharge which is the result of an accidentally quenched superconducting electromagnet. The discussion is based upon the assumption that the electromagnet is the B-field source of a sea-going vessel's magnetohydrodynamic, MHD, power plant. Should such a vessel be one which operates subsurface, it then seems clear that knowledge specific to the vessel's existence and location could in principle revealed by radiations emanating from a bum-out flash. Lightning and the varied nature of its electromagnetic radiations is used as a model to investigate the consequences of an incident of this nature. Further, the electromagnetic radiations resulting from lightning discharges are compared with those expected from the arc discharge which may accompany a superconducting magnet quench. The purpose of this discussion is to suggest the existence of a problem and then to present relevant information dealing with atmospheric and man-made discharges. The hope is that the signature differences in these two types of discharges will be sufficient to make it possible to distinguish atmospheric flashes from man-made flashes, the latter involving energies of order of megajoules.
