Northern Territory at it's Best

[leon]

Hi Guys, just a few more from the Top End.:)

Enjoying ever moment up here, and try to get out as much as possible to capture what I can, I especially like the Sunsets and Sunrises.

Now you have seen the snake ones, so here are a few different ones.

There is a Sunset in there behind the Jetty, the Nightcliff Jetty at Dawn, the Jetty on it's own at dusk, and Parliament House at night, and an early morning fisherman at Nightcliff.

Hope you enjoy them.;)

Leon :thumbsup:

Hi Leon,

Thanks for these beautiful postcards!

The sunset looks just like the Ad for the northern territory, wonder if you can get the green flash.... Worth a try with sunsets like that.

I can feel the warmth just looking at them....ah summery nights.

Thanks guys for your comments, Clive I'm not sure what you mean by the green flash though.

Beautiful pics Leon. :thumbsup:

Darwin has the best sunrises and sunsets, so accessable, and gorgeous over the water.

Havent seen a green flash, but heard about them a few times. Its a flash of green associated with sunrise/sunset ..... light refraction or something.

Many thanks Liz, so that is what is meant by a green flash !!!!

That sunset is a ripper Leon.

Talk about getting itchy feet after seeing those images.

Liz has it.

The reason for green flash optical phenomena lies in refraction of light (as in a prism) in the atmosphere: light moves more slowly in the lower, denser air than in the thinner air above, so sunlight rays follow paths that curve slightly, in the same direction as the curvature of the Earth. Higher frequency light (green/blue) curves more than lower frequency light (red/orange), so green/blue rays from the upper rim of the setting sun remain visible after the red rays are obstructed by the curvature of the earth.
Green flashes are enhanced by mirage, which increase the density gradient in the atmosphere and therefore, increase refraction. A green flash is more likely to be seen in clear air, when more of the light from the setting sun reaches the observer without being scattered. One might expect to see a blue flash, but the blue is preferentially scattered out of the line of sight, and remaining light ends up looking green.
With slight magnification a green rim on the top of the solar disk may be seen on most clear-day sunsets, although the flash or ray effects require a stronger layering of the atmosphere and a mirage, which serves to magnify the green for a fraction of a second to a couple of seconds.

Thanks Clive for that very informative response, i will keep a good look out for that effect, maybe it has happened but i never took any notice, who knows.
