In pouring over data from Australia’s Desert Fireball Network (DFN) — a network of cameras set up across Australia to capture images of minimoon fireballs, or minimoons entering Earth’s atmosphere and burning up — a group of researchers have identified what they think is a minimoon meteor, or fireball.

This is the second time that researchers have identified a TCO blazing through the atmosphere before hitting the ground. In finding the fireball, named DN160822_03, the researchers think that it exploded over the Australian desert on Aug. 22, 2016.
