Ukraine's space agency says a flash of light that appeared on April 19 over the capital was not due to a falling NASA satellite, as earlier reported by the military. The agency said instead that the event was "probably related to the entry of a cosmic body into the dense layers of the atmosphere." NASA has also rejected claims it was its satellite. The light triggered an air alert and prompted the military administration to post messages telling people that air defenses were ready and advising them to stay inside.
