According to this, during the summer we get sunless days? --Ed Poor

Ed, there is of course the same problem with the Antarctic Circle article -- I suspect a cut and paste job. Unless "conjunction" means the opposite of what you and I think, this is a mistake. Also, should the articles make clear that we mean summer in that hemisphere? Slrubenstein

Uh, you guys should feel ok to correct errors like that. I don't think its necessary that the article makes it clear that we mean summer in that hemisphere. The link to summer solstice does make that clear. Lir 21:30 Nov 4, 2002 (UTC)

[edit] It needs a better map

The map up there is quite franky, rubbish. It is merely a re line on an atlas page. It needs a better one! --Differentgravy 22:06, 8 November 2006 (UTC)

Due to precession, the Arctic Circle fluctuates within a band of 250 kilometres, moving by about half a kilometre in one year. Is this true? I've never heard of this phenomenon before and it seems extreme. Any astronomers out there? Arcturus 22:08, 21 Mar 2005 (UTC)

I changed it to be astronomically correct Tom Peters 3-Sep-2005 21:45 UTC

[edit] Iceland

Does Iceland "have significant territory within the Arctic Circle" as claimed by user:70.81.117.175? He has made serveral unconfirmed edits to other pages that have been reverted (by myself and others). However, I'm not sure of this and didn't want to revert what may be true. CambridgeBayWeather 13:04, 2 October 2005 (UTC)

Iceland is south of the arctic circle. It passes through the small Icelandic island of Grimsey, but that's hardly a significant part of the contry's territory. Shanes 16:12, 2 October 2005 (UTC)
Thanks I thought so but was not 100% sure and didn't want to appear to be hounding a particular user. CambridgeBayWeather 03:27, 3 October 2005 (UTC)
Come to think of it, how many countries do have insignificant holdings in the Arctic Circle? If there's just a few they could be added to the article. --Kizor 09:39, 7 October 2005 (UTC)
Apart from those already listed I think only Iceland has any land inside the arctic circle, although it is only a fraction of Grímsey and the islet of Kolbeinsey further north, I don't think it exceeds one square kilometer in all... but still interesting trivia. --Bjarki 22:00, 24 October 2005 (UTC)

[edit] Numbers don't match other Wikipedia article

This line "The main long-term cycle has a period of 41000 years and an amplitude of about 0.68°, or 76 km on the surface." does not jibe with this info "The Earth's axial tilt varies between 21.5° and 24.5° with a 41,000 year periodicity" from Axial_tilt.

That's a 3 degree difference, not .68 degree. If the 3 degree figure is correct, this article needs corrected. It would be nice to add the distance range for the Arctic and Antarctic circles to the Axial tilt article.

[edit] Suggested merge with Antarctic Circle

Much of the discussion here is relevant also to Antarctic Circle.

Rather than have to duplicate info between the pages, how about merging to form Arctic and Antarctic Circles? Currently the discussion of the same issues at Antarctic Circle is less complete, as is symptomatic of the extra maintenance overhead of having it as a separate page.

Your thoughts?

[edit] Incorrect?

Everything north of this circle is known as the Arctic, and <blink> the zone just to the south of this circle is the Northern Temperate Zone.</blink>

This would mean even the Sahara or the South Pole is part of the Northern Temperate Zone. --Abdull 10:52, 26 March 2006 (UTC)

Not really because you would click on the link which goes to Temperate and explains that it runs to the tropics. CambridgeBayWeather (Talk) 14:31, 26 March 2006 (UTC)

[edit] Midnight sun

208.252.179.26 05:17, 11 June 2007 (UTC)Chip W At what lattitude will there be 6 months day, 6 months night? Does it have a name?

The North Pole would probably be the closest. With a latitude of 90 and any longitude you will get sunrise about the 18 March and sunset about 25 September. Check it out here. CambridgeBayWeather (Talk) 07:10, 11 June 2007 (UTC)

208.252.179.27 06:20, 15 June 2007 (UTC)Chip W I checked this out at the aa.usno.navy site you provided, and apparently you're very close to correct. 89 degrees, 52 minutes has one sunrise, one sunset per year. I thought it would be further south.

This is of interest to me since I learned that the Will Steger expedition to the North Pole in the 80's (before GPS) determined they were at the Pole by measuring the sun's height above the horizon. When it stayed the same height for 24 hours, they were at the pole.

[edit] Arctic Circle or the Arctic?

It seems to me that much of the information currently in this article pertains more to the Arctic as a region, rather than to the Arctic Circle, which is just a line of latitude. —Lasunncty 07:41, 14 August 2007 (UTC)

[edit] Geography

edited the * Russia and parts of Ukraine icluding Kiev and Odessa. ... kiev and Odessa are a long way from the arctic circle.. seems like someone was bored.

[edit] Circumference

Much like the Equator's circumference being given as 24,901.5 miles in that article, a useful addition here might be the circumference of the Arctic (and Antarctic for that matter) Circle. Assuming a spherical Earth (close enough, I thought, for a first approximation), I made this out to be around 9,905.2 miles (24901.5*cos(66.56)), yet this source gives a value of nearly 11,000 miles. The latter seems excessive, considering an oblate Earth would suggest a smaller number than my estimate. Can someone with better math skills please confirm the right value? 82.219.212.253 (talk) 17:25, 18 January 2008 (UTC)
