This year, the summer solstice coincides with the Full Strawberry Moon.
First, June's full moon arrives Monday at 7:02 a.m., one hour after it has set below the horizon in Baltimore. Look for it Sunday night, though it won't yet technically be full.
About 12 hours later, spring turns to summer at 6:34 p.m. The solstice is when the North Pole is tilted farthest toward the sun, at an angle of 23.4 degrees. That makes it the "longest" day of the year in the Northern Hemisphere, with more than 14 hours, 56 minutes of sunlight.
Two hours after that, the full moon will still look plenty big when it rises at 8:41 p.m.
A full moon hasn't landed on the solstice since 1948, according to the Old Farmer's Almanac.
