Observations of fireballs emitted periodically from a germanium bulk in a microwave cavity, and traveling along the cavity toward the magnetron, are reported. The effect is associated with a hot spot evolved on the germanium surface. The luminous fireball is created by the hot spot, and then flies away about ∼20 cm to the magnetron, and disappears. Immediately after, the next fireball is generated, travels, and disappears. The fireball lifetime cycle is 1-2 sec, repeating periodically tens times. The paper describes this phenomenon in view of Refs. [1, 2], and discusses its practical significance.
