Some lucky people in the northern reaches of Maine got to catch a glimpse of the Northern Lights.
The National Weather Service bureau out of Caribou tweeted out images Sunday night captured by one of its employees, which show the lights glowing in the skies over Castle Hill, Maine.
The Aurora Borealis are caused by an interaction between the Earth's outer atmosphere and electrically charged particles that the Sun emits. Northern Lights are typically the most visible in areas around the Arctic, or Antarctica to the south, but there have been instances of impressive light displays as far south as Texas in the past.
