Details:
Here are some more images shot with a 10mm wide-angle lens of the aurora Feb 7, 2014 as seen from Churchill, Manitoba from the Churchill Northern Studies Centre. These depict the display early in evening about 10 pm when it appeared as a classic curtain in the sky but hanging across the southern horizon through Orion. The gibbous Moon is just off frame to the right.
The greens were easy to see with the eye but the magentas were visible only by the camera and I have punched up their intensity here.
Two of the images show the launch towers of the now abandoned Churchill Rocket Range. Built in 1957 for the International Geophysical Year, the Rocket Range was in use until the mid-1980s as Canada's only launch facility. Hundreds of sounding rockets, many of them Canadian-built Black Brants, were launched from here, shooting up into the ionosphere to study the aurora. Today, the launch towers and blockhouses are derelict. All efforts to revive the site under private initiatives have failed.
This night, as the aurora display developed it moved to the zenith, shown in one of the images, with the sky also lit by moonlight and with some high haze. But the combination makes for an interesting abstract swirl of light and colour.
