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
Comet Shoemaker–Levy 9 largest impacts. The waves were thought to be travelling within a stable layer acting as a waveguide, and some scientists thought the stable layer must lie within the hypothesised tropospheric water cloud. However, other evidence seemed to indicate that the cometary fragments had not reached the water layer, and the waves were instead propagating within the stratosphere. Radio observations revealed a sharp increase in continuum emission at a wavelength of after the largest impacts, which peaked at 120% of the normal emission from the planet. This was thought to be due to synchrotron radiation, caused by the injection of relativistic
