It's the seventh full moon of the season and expected to reach full phase at 12:07 a.m. ET on Sunday.
If you're fortunate enough to see the full moon at night, hopefully it won't be too stormy to get a good view. For Louisville the moon will peak at about a third of the way up from the horizon tonight and be visible for about 10 hours. Sunday's full moon will have a 99.9% illumination. The Thunder Moon comes from a charmingly obvious point of inspiration - summer is a time of constant thunderstorms around much of the U.S. Algonquins also called it the Full Buck Moon; at this time of year a male deer's antlers are in full growth mode.
It takes the moon 29.5 days to complete an orbit around the Earth. People will have an even better view of the full moon as it rises higher in the sky.
The moon also goes by other names like the Hay Moon, Mead Moon, Ripe Corn Moon. Ancient tribes named July's full moon due to the frequent thunderstorms in the month.
SUMMER MOON The summer heat peaks in July.
