In one of the images a double lunar corona can be seen during the early morning. It is an optical phenomenon characterized by the fact that we observe a halo or disk of soft colors on the outer circumference of the moon.

The Full Beaver Moon, November, is known by this name because this was the time to set beaver traps before the swamps froze completely to ensure a supply of warm furs for the winter.
It is also suggested that the name Full Beaver Moon comes from the fact that beavers actively prepare for winter in the fall. And, also, sometimes, this full moon is also known as the Frozen Moon or Frost Moon.
All the snapshots have been taken from the Fabra Observatory, an exceptional viewpoint given its location on a buttress of the Tibidabo mountain, facing south, at 415 meters above sea level.
