BTW there's 24 hour light in Antarctica during the summer because it's close to the concave mirror and the light wraps around, there is no 24 hour Sun like there is in the Arctic. The Sun scrolls across the horizon like a 2D video game for some hours then goes out of sight while it travels around.
This same effect is observable in Australia to all-be-it to much lesser extent, you can see the sideways motion of the sunlight just before sunrise and just after sunset there.
Why do you have to go to Antarctica? Just fly high enough and take a picture or use a telescope to observe the dome?
I read (((they))) used a giant flash bomb in Antarctica (cover story was the nuke hoax) and got photographs of the dome.
fake edit:
Hey wikileaks, you should hang out some relevant images from Antarctica for a limited time. The images posted so-far leave much to be desired...
