Was there really a blue moon?
When did it happen?
There has been a blue moon. When a large amount of fine dust was sent into the upper atmosphere by huge Canadian forest fires in 1950, the dust caused a blue coloring in various parts of the world. Cars turned on their headlights in the daytime, and at least one daytime baseball game was played under lights. In some places, people even reported a blue sun. The phenomenon lasted at least two days.
