The “solstice moon” will be visible tomorrow night. It just might be the biggest thing you’ve seen in quite some time!
There’s no better time to see it. The full Moon of June 18th is a “solstice moon”, coming only two days before the beginning of northern summer. This is significant because the sun and full Moon are like kids on a see-saw; when one is high, the other is low. This week’s high solstice sun gives us a low, horizon-hugging Moon and a strong Moon Illusion.
NASA explains how the illusion works. Link
