Anthony Wesley in New South Wales, Australia reported yesterday on IceInSpace.com.au that "at approximately 20:30utc this morning I recorded a large fireball on Jupiter." This is the same amateur who discovered an impact plume on Jupiter one year ago next month. That event was followed up by many observers, including with the Hubble Space Telescope, about which a news item was coincidentally released yesterday. SpaceWeather.com is reporting that Christopher Go in the Philippines also recorded the flash. Image from Anthony Wesley from 2031:29 UTC (north is up).
