Hi
The diagram below is a mock up (not to scale obv) of Jupiter and 4 moons - seen on the 24/11/10 at about 7pm from Kerry.

Can anyone give me any pointers on identifying them correctly- both tonight and in the future?

Regards

Nick

Hi Nick,

There are several online tools that allow you to see the positions of Jupiter's moons at any date and time that you specify. Links to two such sites are below:

www.skyandtelescope.com/observing/object...ascript/3307071.html
www.shallowsky.com/jupiter.html

Alternatively, download the free planetarium programme "Stellarium". It has really nice graphics and will allow you to zoom in on Jupiter, and many other astronomical objects, so see the positions of its moons. Again you can change the time if you wish. Download it (PC, Mac & Linux versions) from:

www.stellarium.org/

Cheers, Mike.

No problem, always happy to take pity on a City fan. ;)

Have you heard the one about the Manchester City (replace with your least favourite Club) fan who tried to jump of the top of the main stand at old Trafford (replace with ground of your least favourite Club's local rivals)?


Well, the Old Trafford groundsman came in early one Friday morning to find a crowd of people staring at something on top of the stand. Looking up, he sees a man dressed in the blue of small local club Man City standing on top of the stand right at the edge of the 100 foot drop onto Sir Matt Busby Way.

"What the bloody hell are you doing up there" shouted the groundsman, "Get down before you fall and kill yourself". "That's exactly what I'm going to do" replied the City fan. "I've been supporting City since I was a lad, and in all that time they've never won anything". "They're rubbish, and yesterday's loss to Lech Poznan was the last straw." I've had enough, I can't take it any more, I'm going to kill myself."

The onlookers eventually persuaded the City fan that there was some hope, and he agreed to climb back down off the stand. When he was safely back on the ground the groundsman went up to him. "I'm puzzled" he said, "If you're a City fan, why did you come to Old Trafford to kill yourself?" "Why didn't you try to jump off the stand in Eastlands?"








(Wait for it.)




















"Are you joking?" said the City fan. "Have you seen to queues over there!"
