Could you elaborate on the rarity of a moon dog? Is it a frequently observed phenomenon, or does it occur only in rare and specific circumstances? I'm curious to know if it's something that most people are likely to witness in their lifetime, or if it's truly a once-in-a-blue-moon sighting. What factors contribute to its rarity, and how do they come together to create this unique optical illusion? I'd appreciate a concise yet detailed explanation of the conditions necessary for a moon dog to occur.

    The rarity of moon dogs in comparison to sun dogs lies in the specific conditions required for their observation.

    Sun dogs, being a more common phenomenon, can be observed under a wider range of conditions.

    However, moon dogs require a much brighter moon, specifically a quarter moon or brighter, to be visible.

    This condition of a sufficiently illuminated moon is less frequently met, thus making moon dogs a rarer sight.
