Remember the "supermoon" of March 2011? The full moon appeared larger than usual because of its proximity to Earth. This month's full moon, known as the Full Flower Moon, could be almost as spectacular.
That's because it will be nearly as close as it was last March. It will be about 250 miles further from Earth than the 221,000 mile-distance it was March 19, 2011. The moon's average distance from Earth is about 239,000 miles, according to EarthSky.org.
The full moon arrives at 11:35 p.m. Saturday, within an hour of the moon's perigee. That means the moon will be at its closest to the Earth for this year. It's relatively rare that the full moon coincides with perigee, happening once every 13 months or so.
Aside from a nice photo opportunity when the moon dwarfs buildings on the horizon, the supermoon means higher than normal tides, so be wary of that if you live on the bay.
