Information about the yearly sunrise
at the North Pole
(From Wayne Davidson, our Meteorological Observer based in Resolute Bay)
The actual yearly sunrise moment at the North Pole, based on Resolute Bay Canada data, is about March 15 at about 10 pm Eastern standard time. Not at the Equinox on March 21.
This is due to atmospheric refraction, which is largely ignored even in modern textbooks. Cold air combined with temperature inversions, the phenomena which causes mirages, combine in very thick nearly horizontal air layer and create an amazingly slow but gradual sunrise, starting with the 24 hour sun line.
Only at the South Pole in Antarctica can this be seen.
I chose March 13, 2010 Resolute sunset pictures, as something similar to a slow but gradual expanding sun disk which literally takes days before it becomes a complete flattened disk, which should occur on March 18 at the Pole. Come the day of the Equinox the sun is well above the horizon almost round or ovoid, being in pristine air, the sun then appears bright yellow, so bright it cant be looked at.
Reverse the order of pictures taken on March 13, 2010 sequence. Every picture may encapsulate a day, the bottom March 15 at the Pole, the top March 21.
The top picture was taken with a million to one reducing sunlight brightness filter, the sun disk was extremely bright, continued being bright even at -1.5 degrees below the horizon, something occurring each year on about March 16 at the Pole. So bright it can't be watched even with an eight of its size.
Flying to the Pole is possible much earlier than at the Spring Equinox given a good clear day, eventually Global Warming will make this sunrise myth a bit truer, but good light and contrast would subsist even in much warmer clear air.
For now, all that is needed is to look at Polar light features during Arctic locations having the same sun altitudes, it may be very convincing if time is taken to observe. One day, a plane will land at the Pole during the Spring Equinox once the Myth of the sun rising first on March 21 at the North Pole is finally broken.
