Question

When the Arctic Circle experiences 24 hours of daylight, what is happening in the Antarctic Circle?

Answer 1

The opposite (or almost).

On the day of the solstice (around June 21), people on the arctic circle see the sun get lower and lower (to the west, the north west and finally north) but it does not set.  It skims the horizon.

Theoretically, people on the antarctic circle would see twilight in the north east, then NNE then very bright twilight due north, but the sun would not rise above the horizon.  In reality, because of the refraction of the air, the image of the sun is raised by almost a degree (almost twice its apparent diameter), so that a person on the antarctic circle would see the sun rise barely above the horizon, near noon, then start setting almost immediately (actually, sunset would take some time because the sun's apparent movement is almost parallel to the horizon).

Answer 2

24 hours of night light

Answer 3

The opposite.  24 hours of the sun hovering the horizon (nightfall).  This occurs on June 21st most years.
