The surprising impact on Jupiter was first reported by amateur astronomer Dan Peterson
of Racine, Wisc., who was observing the largest planet in our solar
system when the event occurred, according to the website
Spaceweather.com, which tracks space weather and night sky events.


"It was a bright flash that lasted only 1.5 – 2 seconds," Peterson told Spaceweather.com.
Peterson used a Meade 12-inch LX200GPS telescope to observe the event,
which occurred near the southern edge of Jupiter's northern equatorial
belt of clouds.
