Taken last march in Orkney, with D70. It was cold, just got back from pub and grabbed camera and tripod,

The sodium lighting is Finstown, a village just over a mile away.

Thats a really cool image Nabban, really weird effect with the green, nice one!! What was the exposure time?

[Naz]

I will check the exif and see what the exposure and lens setting etc tomorrow, have to dig the cd out with the original raw file on it. Do that in the morning.

Thanks for sharing Nabban.

Have you considered submitting it to a magazine?

Hi Steve, I have checked the exposure details for the photo, here goes.

30 sec exposure, at f3.5, focal length 18mm, ISO 1000.

I did submit to the BBC Sky at Night web site but no joy. will look at one of the magazines.

I have loaded a one from the same sequence.

I did see a green aurora about 10 years ago. Very cool. Sometimes the sky was entirely lit up, and for a while, there was just a green band along the horizon, with brighter pulses flowing along it. Watched for ages. Nice pic.

Awesome picture Nabban

Northern lights are caused by light emitted from atoms in the

atmosphere which are excited by charged particles trapped in and

leaking out of the van Allen radiation belts. These are places

where the charged particles are trapped by the magnetic field of

the earth. The belts, of course, come into the earth's

atmosphere around the earth's magnetic poles, which is why the

aurora is mainly near the north and south poles of the earth.

Anyway, the light emitted is characteristic of the atoms making

up the atmosphere of the earth which are, of course, mainly

nitrogen, oxygen, and hydrogen and so the colors are

characteristic of these atoms.

Further explanations of northern lights are available many

places. You might enjoy clicking on the URL below, which I found

to be a good explanation.

thats really cool Nabban. Really surprised S@N did nothing with it. I'm sure the magazines would publish it though.

Only seen Aurora once and that was October 2003. It rarely makes an appearance this far south

Sorry,not the S@N magazine, submitted to the BBC website for inclusion in the site / programme, the magazine wasn't around at the time, will now submit to the mag.

That October 2003 display was spectacular, I believe it was visible as far south as the northern Mediterranean.

I observed it, but didn't have a camera to hand, so missed it .
