Due to the unclear origin of the detections at first, the radio signals were named after the peryton, a mythical winged stag that casts the shadow of a man.
[5] These signals mimicked some aspects of FRBs that appeared to be coming from outside the Milky Way galaxy,[2][7] but the possibility of their having an astronomical origin was soon excluded.
[8][9][10] To track activities near the telescope, the Commonwealth Scientific and Industrial Research Organization (CSIRO) installed a radio frequency interference (RFI) monitor at the Parkes site in December 2014.
This form of monitoring became more common as radio-emitting devices became more prevalent on radio telescope sites, including mobile phones, Wi-Fi, and digital televisions.
Each peryton event was accompanied by a period of radio emission at a frequency of 2.5 GHz that was outside the telescope's field of view.
[5] The microwave oven releases a frequency-swept radio pulse that mimics an FRB as the magnetron turns off.
