The nearly full Moon will be visible on Saturday evening and is a super full moon at 6:33 a.m. Sunday. It rises again on Sunday evening and will be visible once again.
The term “supermoon” was first coined by astrologer Richard Nolle to describe the full or new Moon when it's less than 223,000 miles from Earth. That’s about 6% closer than the average Earth-Moon distance, which is 239,000 miles.
Despite being closer than usual, supermoons are rather ordinary and, by Nolle’s definition, take place several times a year. The supermoon this weekend will only be about 7% larger than the average full moon.
This weekend's supermoon will also bring the largest tides of 2013, because a closer Moon exerts a stronger gravitational pull, creating more variation between the tides.
The moon won't be noticeably bigger on the night of the supermoon but it sure looks that way especially at it rises. The so-called Moon Illusion causes the Moon to appear bigger when viewed along the horizon and can fool people into believing the supermoon myth.
The only thing that may come in the way of you viewing the moon this weekend will be clouds from showers and storms. Good luck and share pictures!
