Conditions should be good for Oklahomans to view the "strawberry moon" Monday night.
A strawberry moon is a full moon that appears very close to the summer solstice. In the northern hemisphere, the summer solstice is the point in the year when the sun stops moving north, producing the longest amount of daylight in a single day of the year.
Native American tribes named the phenomenon the strawberry moon long ago.
The web site atlasobscura.com compiled some interesting information about how rare the event is.
According to the site, this year the exact moment of the summer solstice will be 5:34 p.m. Oklahoma time on June 20, 2016. The moon reached its full phase at 6:02 a.m. Oklahoma time Monday morning.
The last time the two events happened within 24 hours of each other was in 2005. The last time they occurred within a 12-hour period was 1986.
In 1967, the summer solstice and the full moon occurred about two-and-a-half hours apart. In 1948, the events were only 43 minutes apart.
