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
Great Comet of 1744 "dust striae" seen in the tails of some comets, such as Comet West and C/2006 P1 (McNaught). Chéseaux, on March 9, was the last known observer in the northern hemisphere to see the comet, but it remained visible for observers in the southern hemisphere, some of whom reported a tail length of approximately 90 degrees on March 18. The comet was not seen after April 22, 1744. The comet also was noted in Japanese astronomical records in the "Nihon Odai Ichiran" of the Kanpō era. Researchers have found in Chinese astronomical records that some Chinese observations describe audible sounds associated
