Impact Spot on Jupiter

[icytailmark (Mark)]

I just saw a tiny black spot on Jupiter i think its the impact spot but im not 100% certain. Can anyone else confirm this?

If it's a tiny black spot it will be the shadow of Io which is currently transiting the face of Jupiter. Good observation anyway!

its getting a little faint to see visuably unless you have large appature or image

yeh it's much fainter than a shadow transit these days. Anthony (bird) has a recent image in the Solar System forum which shows how it currently looks.

It would be near impossible to observe visually, now.

Difficult I think, but not impossible. Having said that, its pretty clear that icytailmark has seen a moon shadow. I last saw the impact site on 20th August at Mudgee with 46cm at x247 in goodish seeing. It was a little difficult to separate from its surroundings but looked like two adjacent, mod elongated, smallish, greyish, slightly darker smudges with diffuse edges and consistent shade & colour (not darker at centre). They were connected by a short thin wisp.

That was nearly 2 weeks ago now though ...


Best,

Hello,

I don't think the spot is visible anymore. We've observed it about a month ago and it was clearly visible in a 20 cm newton and 28 cm SCT. A friend of mine, that has very good eyes, also saw it in 15 cm refractor.

When I watched yesterday and a day before yesterday I just couldn't see it, even after 15 minutes of observation. It is also true that I only watched through a 12.7 cm refractor. The impact is also much closer to the pole, than moon shadow transits, which mostly occur in the equatorial zones
