Another fireball on Jupiter?
An amateur astronomer reported the visual detection of a fireball on Jupiter at 11:35 UT (September 10 2012) last night. It was confirmed on a video recorded from Texas. This is the 6th impact of Jupiter detected so far.
Astronomer Dan Petersen saw today September 10 2012 at 11:35 UT a bright flash on Jupiter which lasted 1 or 2 seconds. It estimated its position to be in the system I Longitude = 335 and Latitude = +12 deg. The report was sent to Richard Schmude of the Association of Lunar and Planetary Observers (ALPO) and forwarded to us by John H. Rogers, Jupiter Section Director at the British Astronomical Association.
A video of the flash was revealed a few hours later by George Hall, an amateur astronomer located in Dallas Texas. He used a webcam mounted on a MEADE 12″ LX200GPS. An image extracted from the video is attached above and it looks quite similar to the flash observed on August 20 2010.
This is the 6th impact observed on Jupiter. The most famous one was the predicted, and intensively observed, impact of the comet Shoemaeker-Levy 9 (S-L 9) which broke apart and collide on Jupiter in July 1994. An fireball was photographed by Voyager 1 during its encounter on March 1979 with Jupiter. More recently, thanks to the intensive monitoring of amateur astronomer and the improvement in image quality providing by cheap webcam plugged on small telescopes, several small impacts were detected and followed up by amateur and professional astronomers together:
