Aurora Borealis

Aurora Borealis, also known as the Northern Lights, is a natural phenomenon of lights in the night sky in the northern-most regions of the world. The event is named after the Greek goddess of dawn, Aurora.

History
In 2003, during the night before the Wiccan Festival of Lights, an Aurora Borealis occurred. The day afterward, magic vanished and according to Phoebe three planets - Jupiter, Mars, and Saturn were all in Gemini, which happened once every three hundred years. It was later revealed by Merrill that all these signs were part of a prophecy predicting the arrival of the Twice-Blessed Child. When Wyatt was born, magic was returned to the world.

Destined History
Prue Halliwell was born on the same day as her cousin Wyatt, making her a Twice Blessed Child as well. Magic once again vanished from the world until she was born. It's possible that the Aurora Borealis took place on the night before Prue was born, as it would make sense. However, Jupiter, Mars, and Saturn couldn't have been in Gemini since it hadn't been another three hundred years. It's also unknown if the Wiccan Festival of Lights had been celebrated the night before Prue's birth too. But only one can theorize this possibility.
