2010 Jupiter impact event about two seconds. It was located in the South Equatorial Belt, about fifty degrees from the central meridian. The June 2010 superbolide impactor probably measured between 8–13 meters across, with a mass between 500–2000 metric tons. Jupiter probably gets hit by several objects of this size each year. On 20 August 2010 UT, yet another flash event was detected on Jupiter. As of August 23 two other observers had recorded the same event. In July 1994 the Comet Shoemaker–Levy 9 broke apart and collided with Jupiter, resulting in a series of hits. This incident had been predicted in advance. On
