Last night Antony Wesley reported an impact on Jupiter (in a video, he saw a fireball erupting). Now it has been confirmed through similar observations made by Christopher Go. His running log of Jupiter images is here. Presently, there’s no sign of a cinder cloud (as was the case in some of the Shoemaker-Levy 9 impacts in 1994), but observers are keeping an eye out just in case. Jupiter is presently a predawn object in Kendal’s skies, not good for getting out intricate details, but worth a look as it is missing one of its usual two dark belts visible in moderate telescopes.
Wesley’s video of the impact is below:
