Jupiter and the Moon

If you are lucky enough to have clear skies tonight, and don't count on it in Scotland, you may be able to see Jupiter pass within six degrees, and a little to the left, of the Moon. Now, to be clear, this is not technically NOT a conjunction, but they will look close. Technically conjunctions are defined as occuring when two astronomical objects have either the same right ascension or the same ecliptical longitude, normally when observed from the Earth. This can happen between planets, planets and the Moon, sometimes (very rarely) more than two objects may be involved. Often they just appear close, sometimes much closer, and sometimes very close. Last year was better for the Moon and Jupiter. The image below shows a Stellarium screenshot of how it will appear tonight from Scotland.


Last year I was lucky enough to get a decent photo of Jupiter and the Moon when they appeared slightly closer in the sky . The photo below is a composite shot, but shows their actual positions.





I took three separate images, as it is impossible to capture all the detail in one exposure. I took one photo of the Moon, one of Jupiter and one of Jupiter's moons, all using a Fuji high zoom bridge camera. I then built the image in Gimp. If you have clear skies, head out for a look. Better still, take a photo!
