Reminiscent of Our Lady's warning about this being a harbinger of war/chastisement?
When we had red auroras back in 1938, this was Our Lady's warning sign.
In 1938, the midnight skies had brilliant red auroras, so that the entire sky was red, and even the ground was tinted with red. It was eerie. Not only did Fatima writers mention this "miracle", but also the book
Divine Mercy discussed this event.
My husband was only three at the time, but the news of red skies being seen globally even down to the equatorial regions of Cuba had a huge impact on him. Being a toddler, he was not allowed to go out after dark to see these red skies. However, he remembers seeing and reading the newspaper headlines of red skies with red arrows showing the movements of Hitler's troops. My husband started reading at two because he enjoyed the comic strips. He also read the encyclopedias around his home. The movement of Hitler's armies, navy, and air forces, and the constant threat of a world war encouraged him to learn to read.
In addition, scenes of the red skies and Hitler's troop movements were shown in newsreels at the movie theaters where children's movies, such as Boy's Town and The Adventures of Robin Hood were played.
