TUS (Tracking Ultraviolet Set-up) is the world’s first orbital detector of ultra-high-energy cosmic rays (UHECRs). It was launched into orbit on April 28, 2016, as a part of the scientific payload of the Lomonosov satellite. The main aim of the mission was to test the technique of measuring the ultraviolet fluorescence and Cherenkov radiation of extensive air showers generated by primary cosmic rays with energies above $\sim$100 EeV in the nocturnal atmosphere of the Earth from space. During its operation period, TUS registered almost 80,000 events, with a few of them satisfying the criteria expected for UHECR candidate events. Here we discuss the phenomenology and possible interpretations of an outstanding event registered in perfect observational conditions on October 3, 2016.
