The solar parhelion, commonly known as a sun dog, has a rich history intertwined with observations of celestial phenomena

In ancient Greece, Aristotle and Theophrastus described atmospheric phenomena, including halos around the sun, likely encompassing sun dogs. However, the term "parhelion" itself emerged later, around the 17th century, as scientists sought to understand and categorize these optical phenomena.

Throughout history, interpretations of sun dogs varied across cultures. Some perceived them as omens or mystical signs, while others approached them with scientific curiosity. Scientists like Descartes and Kepler contributed to understanding the physics behind these phenomena, attributing them to the refraction and dispersion of sunlight through ice crystals in the atmosphere.

The term "sun dog" is believed to have originated from the idea that these bright spots near the sun followed it like loyal companions, akin to dogs following their master.

As scientific understanding advanced, observations of sun dogs contributed to meteorology, aiding in the comprehension of atmospheric optics and the behavior of light passing through ice crystals. Today, sun dogs continue to captivate observers worldwide, not only for their scientific significance but also for their breathtaking beauty in the skies.
