We know it as a Bright Spot or Sun Dog, it is an atmospheric phenomenon known as a Parhelion.
Below is an oil on canvas painting, called the Vadersotstavlan depicting this event, it is thought to be the oldest Swedish landscape painting and the oldest depiction of a Parhelion.
The Vaderstostavlan has come to represent the history of Stockholm and has appeared on many different objects over the years such as stamps, banknotes and in 1998 it appears as a mural by artist Goran Dahl on the walls of the cities metro station.
The most famous Parhelion that we lovers of English history remember appeared on the 2nd February 1461 at the Battle of Mortimer's Cross, Edward IV considered it a sign from God that he would win the battle. Edward thought it represented the Holy Trinity and that God was on his side. It is from this beautiful sight he took his emblem, the Sun in Splendor.
