Description
Moon in black night sky, showing 99% illuminated waning gibbous moon phase on Saturday, October 31st. The second full moon of the month. A Halloween full Hunterââ¬â¢s Moon and Blue Moon. The `once in a blue moon` phenomenon does not necessarily mean the moon will look blue on Halloween. While the dark blue tone of an evening sky can affect the coloring we see, Earth`s satellite will most likely not appear blue at all.
