dayyers

Dayyers are a rare and poorly understood phenomenon observed in certain high-latitude and high-altitude regions of the world. The term "dayyer" is derived from the Slovenian word for "day" and "blue" or "cloud", and refers to a rare atmospheric optical effect in which the sky appears as a mixture of daytime and nocturnal colors.

Dayyers are characterized by a distinctive hue that is typically more pronounced than a standard sunset or sunrise. The colors observed during a dayyer can range from pale blue to deep purple, often accompanied by iridescent greens and golds. These colors are thought to be caused by the scattering of sunlight by atmospheric particles and water droplets at high altitudes.

Daughters of dayyers have been observed to create prolonged periods of crepuscular light, where the sun remains above the horizon for as much as an hour after its official setting. During this time, the sky takes on an otherworldly quality, with bands of twilight colors interleaving with patches of full daylight and starlight.

Although the exact mechanisms driving dayyers are not yet fully understood, researchers believe that they are likely caused by unique combinations of atmospheric pressure, temperature, and humidity in regions with distinctive weather patterns. While dayyers are relatively rare, they have been reported in over a dozen countries around the world and are considered a major natural phenomenon worthy of further study.
