On 11 September 2013 the “Moon Impacts Detection and Analysis System” (MIDAS) camera captured a bright 8-second long flash on the central nearside of the Moon. This was the brightest event captured so far by the MIDAS team, and they estimated that the crater should be between 46 and 56 meters in diameter. The LROC team targeted the reported coordinates (17.2°S, 339.5°E) of the flash and acquired several images over a few months until the crater was found on 13 April 2014!
Fortunately there was a NAC image of the target area acquired before the impact, so finding the new crater was relatively easy once an “after” image with comparable lighting to the “before” image was acquired. As it turns out the new crater is ~34 meters (112 feet) in diameter and is located at 17.167°S, 339.559°E, only 3 kilometers (1.9 miles) from the original telescope-based prediction. In the before-after animation you can see ejecta effects from the crater extend out more than 500 meters in all directions!
