This week's full moon hangs lower in the sky than any full moon since June 1987, so the Moon Illusion is going to be extra strong.
What makes the moon so low? It's summer. Remember, the sun and the full Moon are on opposite sides of the sky. During summer the sun is high, which means the full moon must be low. This week’s full moon occurs on June 22nd, barely a day after the summer solstice on June 21st--perfect timing for the Moon Illusion.
There's a table of moonrise times for various cities. Check it out and step outside this week.
