Discovered a week ago by an Austrailian amateur astronomer - an apparent scar on Jupiter's upper clouds caused by a comet or asteroid impact - see spaceweather.com for more info.
Last night as Jupiter was rising in Capricornus in the SE after dusk I had a brief look through my 12" SCT but hopeless view of Jupiter due to its low altitude causing a 'boiling' image. Jupiter soon rose into my neighbour's willow tree and wouldn't reappear for several hours - by then the asteroid 'scar' would have rotated out of view - ho hum
Anyway got a wideangle shot of Jupiter before it entered treeland with planet Neptune too in the field of view some 10,000 fainter than Jupiter in a 10s exposure via my e-finder. Enjoy
