Amateur astrophotographer Ethan Chappel was using his telescope to look for Perseid meteors on Wednesday night when he happened to capture an image of something very large slamming into Jupiter. It was most likely a massive meteor. From Sky and Telescope:
After running the camera data through a program designed to alert the user to just such transient events, Chappel spotted a flash of light in the planet's South Equatorial Belt (SEB). It expanded from a pinpoint to a small dot before fading away — telltale signs of a possible impact based on previous events observed at Jupiter….
If confirmed this would be the 7th recorded impact at the solar system's biggest planet since July 1994, when 21 fragments of Comet Shoemaker-Levy 9 slammed into the planet in succession to create a rosary of dark impact boils visible in amateur telescopes.
Imaged Jupiter tonight. Looks awfully like an impact flash in the SEB. Happened on 2019-08-07 at 4:07 UTC. pic.twitter.com/KSis9RZrgP
