Wiki FRB - see "2010": In 2010 there was a report of 16 similar FRB pulses, clearly of terrestrial origin, detected by the Parkes radio telescope and given the name perytons. In 2015 perytons were shown to be generated when microwave oven doors were opened during a heating cycle, with detected emission being generated by the microwave oven's magnetron tube as it was being powered off.
I am glad you posted your article since I remember the Australians getting all excited about signals from deep space that turned out to be from a nearby microwave oven when the microwave door was opened before the microwave shut off. - Tom
