May 20, 2019 12:17 AM ACST – The Center for Near Earth Object Studies (CNEOS), is part of the California Institute of Technology's Jet Propulsion Laboratory. CNEOS collects data from U.S. Government sensors, and releases it for... reported a 0.11 kiloton event in Australia’s Northern Territory, near the town of Alice Springs. This was a large fireball, which came in at a very steep angle and there are likely meteorites on the ground. However, there is significant uncertainty as to the exact location of the fireball, so the search area is large. Please review the links below and the attached files for detailed info.
