We propose a test for searching pre-supernova collapsing stars using non-thermal emission generated during collapse when the stellar magnetosphere compresses and its magnetic field increases considerably. In a stellar magnetosphere an electric field that accelerates charged particles is produced. Moving in the magnetic field, these particles generate non-thermal radiation. Thus before a supernova flares, the pre-supernova collapsing star can be a powerful source of non-thermal radiation bursts. These bursts can be observed by means of modern instruments (radio, X-ray and gamma-ray telescopes).
