CINCINNATI -- Tri-State stargazers, we hope you marked your calendars for this weekend.
Viewers in the Northern Hemisphere were treated Sunday to a "supermoon" and the annual Perseid meteor shower -- at the same time.
According to EarthSky.org , supermoons occur when new or full moons are at or near their closest approach to Earth in a given orbit.
So far this year, we have had supermoons on Jan. 1, Jan. 30 and July 12. The fifth and final supermoon of the year will be Sept. 9.
The weekend's supermoon was actually be the largest and brightest of the year, an "extra supermoon" if you will, as the Earth was at its closest distance to the moon -- just 221,765 miles (356,896 kilometers) away. That's about 30,000 kilometers closer than the average distance between Earth and the moon.
The best time to catch the supermoon was just after your local sunset when the full moon begins to rise. Miss it because of cloudy skies or poor planning? Don't worry, we've got a few amazing photos from NASA photographer Bill Ingalls .
In a tradeoff, the supermoon could affect your view of the annual Perseid meteor shower, according to Space.com.
The Perseid meteor shower occurs each year as space debris from the Swift-Tuttle comet strikes Earth's atmosphere.
Between Aug. 10 and Aug. 13, the meteor shower will peak and should last for another week. As many as 100 shooting stars are normally visible each hour. Space.com, however, suggests scouting the fireballs in the predawn hours in the days ahead of the night of a full moon.
