just left of the moon,is that really Jupiter?

[glyn lacey]

Just gotta tell someone,got out my dob 130p ,had a big WOw moment just looking at the moon , then the bright light to the left,was that Jupiter and I think 5 moons ? , if so ,worth every penny already.better go to the doctors ,think I've got the bug !!.

[knobby]

Yep, Jupiter it was !

well done

[Langy]

Yes but I think you may find it's  4 moons, the other may be a distant star.

Do you have Stellarium? If not it's a free download most valuable and it will show you what you are looking at as well as how to find objects.

The bug gets worse, especially with this poor weather.

Yep - Jupiter with the moons Callisto, Ganymede and Europa on one side and Io on the other tonight. And the Great Red Spot just about in the center of the planets disk right now too

I was looking up at the Moon and Jupiter around 6.30 last night when the ISS suddenly showed up. I looked around me (in the Aldi carpark) but there was no one nearby that I could try to get excited about it all! So I stood there with my personal Wow moment until the ISS passed into Earth shadow.

Yes it was Jupiter. Got a really great view of it and its 4 Galileans satellites. The Moon was so bright I could barely last a couple of minutes watching it (I still don't have any moon filter yet).

Funny how I wanted the moon to show up 2 weeks ago and now I just want it to go back hiding so I can check better at DSO :-)

Great night last night in Quebec, though ended early by clouds at 8:30pm.

I was looking at that too last night,although the air wasn't too good, lots of wobbling in the camera. The other thing I couldn't understand was that according to Stellarium Jupiter was in the wrong place ??

Well done, a great sight, unfortunately clouded out here, again 

For info. on Jupiter's moons have a look here:- http://www.skyandtelescope.com/observing/objects/javascript/jupiter#

For transits of GRS go here:- http://www.skyandtelescope.com/observing/objects/planets/3304091.html?page=1&c=y

Good luck.

How long is the GRS visible for?

[Langy]

If you look at the link given there is a calculator in there for times, by the looks of things it about every 10 hours.

[Gomtuu]

How long is the GRS visible for?

Sidereal period is just under ten hours, so it's visible for roughly 5 hours in every 10.

I use this free app on my iphone. It has a couple of typos in the moons' names, but it's excellent for giving both their positions and the GRS transits.

thanks for replies.

So if it was visible at 22.56hrs tonight there would be plenty of time to see it and not just at that exact time, 22.55 it wouldn't be there and 22.57 it would be gone.

I'll have to have a look at that app, see if I can get hold of it on android.

Yep, there'll be plenty of time to see the transit. The times on the Sky and Telescope site are for when the GRS is in the centre of Jupiter, so there's a good 50mins before and after that when the GRS will be at its best.

Cheers
