These signals mimic fast radio bursts, pulses that appear to be coming from outside of our galaxy. These perytons were found to be the result of premature opening of microwave oven doors, which releases a frequency-swept radio pulse that mimics an FRB, as the magnetron turns off.
These signals are sidelobes captured by the antenna. Perytons occur at high altitudes above the horizon and show frequency dispersion, unlike FRB. Perytons often occur as a result of periodic bursts. Recombination of three carriers or synchrotron radiation of a decaying magnetic field are potential causal mechanisms.
Other potential sources of Perytons include:
- Signals from aircraft
- Flashes in the ionosphere
- Solar flares
- Terrestrial gamma-ray bursts
- Narrow bipolar pulse. These are electrical discharges between clouds at high altitude with a capacity of several hundred GW
