Heads up - Jupiter - 9th Sep 8pm

[dweller25]

The great red spot will be visible tonight just as its getting dark.

Fingers crossed for clear skies 🤞

Thanks David.

Very clear skies here and my dob is out cooling

[dweller25]

GRS visible now but seeing not great

[dweller25]

Can make out orange hue to GRS now

[David Levi]

I can make out the GRS but the atmosphere is very wobbly.

Yes 😕

[dweller25]

GRS just past central now

[John]

Seeing a bit wobbly here as well but the view is OK.

Does make me hanker for the days when Jupiter was high in the sky though. The details that my 12 inch dob would show back then far surpass what can be made out with it this low in the sky

GRS seems a little smaller than in previous years perhaps ?

Didn't they say it's been shrinking over the last few decades?🤔

I put the Dob out at 840, had a quick look almost straight away and sure enough the GRS was there. Its the first time I've seen it, a bit "wobbly" but very visible. I'll be going out again shortly now the scope's cooled.

That wasn't meant to happen...

Here as well. All going really well until that !

I baged a couple of thousand frames of Jupiter data from around 21:45. Won't be able to process till at least tomorrow evening if not later.

Where do you get this information? It would be good to have it on hand.

Astronomy Now magazine lists the times of the favourable transits visible from the UK.

I use an ios app called gas giants

Attempted to photograph the GRS transit last night.

At my location the southern view was completely obscured by clouds at 20.30, the time of the transit, but it did clear an hour later, although viewing conditions were rather unsteady. I obtained the following image at around 21.30 shortly before Jupiter went behind a tree from my location., and is the first image I have taken showing the GRS.

The image was taken from a 1 minute video using a Canon 6D digital SLR through my 14in Newtonian using eyepiece projection with a 9.7 mm Plossl eyepiece, converted in PIPP, and processed using Registax and Adobe Lightroom.

I assume the info won't be specific to the UK, so you need to work out which transits will be visible from the UK, and which ones will be at a reasonable altitude, Astronomy Now magazine just lists the best ones from the UK.
