In Abram Palmer's 1882 book Folk-etymology: A Dictionary of Verbal Corruptions Or Words Perverted in Form Or Meaning, by False Derivation Or Mistaken Analogy, sun-dogs are defined: The phenomena [sic] of false suns which sometimes attend or dog the true when seen through the mist (parhelions). The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Cf.

Mars might have sun dogs formed by both water-ice and CO2-ice. They are also associated with 22-degree halos. Sun dogs occur when the Sun or Moon shines through a thin cirrus cloud composed of hexagonal ice crystals falling with their principal axes vertical, as opposed to the halo phenomenon that occurs when the principal axes are randomly arranged in a plane perpendicular to the Sun’s or Moon’s rays. Sun dogs are best seen and most conspicuous when the Sun is near the horizon. Hoping to end speculations, the Chancellor and Lutheran scholar Olaus Petri (1493–1552) ordered a painting to be produced documenting the event.

[5], The same plate-shaped ice crystals that cause sun dogs are also responsible for the colorful circumzenithal arc, meaning that these two types of halo tend to co-occur. On 20 February 1661 the people of Danzig witnessed a complex halo display, described by Georg Fehlau in a pamphlet, the Sevenfold Sun Miracle, and again the following year by Johannes Hevelius in his book, Mercurius in Sole visus Gedani.

I feel this was no small miracle…[23], The observation most likely occurred in Auspitz (Hustopeče), Moravia on 31 October 1533. The Sun is a very stable source of energy; its radiative output, called the solar constant, is 1.366 kilowatts per square metre at Earth and varies by no more than 0.1 percent. You don’t have to tell dog lovers the feeling is both mutual (and very real), but a new study published in the journal Science reveals the fascinating reason why we feel so close to our furry companions: When humans and dogs look into each other’s eyes, both get a boost of the feel-good hormone oxytocin, which is the same hormone behind the special bond between new parents and their … On the gas giant planets—Jupiter, Saturn, Uranus, and Neptune—other crystals form clouds of ammonia, methane, and other substances that can produce halos with four or more sun dogs.[8]. The exact etymology of sun dog largely remains a mystery.
