While a blue moon is the second full moon in a calendar month, a black moon is the third new moon in a season of four new moons. The current season began with the summer solstice on June 20 and ends with the equinox on September 22. There were new moons on June 25 and July 24, and there will be more on August 23 (the black moon) and September 21: That makes four new moons in a season, which only happens once every 33 months.
While the black moon can't be seen with the naked eye, the presence of one does make for optimal stargazing conditions.

How to Make the Most of the Black Moon in Denver?
While you won't be able to see the black moon itself, the timing of this moonless night offers stargazers optimal conditions for viewing a moonless summer sky while the Milky Way is at its prime viewing condition from the Northern Hemisphere.Live Science recommends finding the three bright stars of the Summer Triangle in the southeast — Vega, Deneb and Altair — as the Milky Way will be streaming through the left side of the Summer Triangle and down to the southern horizon.
It's best to look at the sky away from light pollution. So head toone of Colorado's many designated Dark Sky Places, or a less-populated spot in the mountains.
We recommend Browns Canyon National Monument, two hours southwest of Denver, which has campgrounds available for $28 per night, or Great Sand Dunes National Park and Preserve in Mosca, where you can view the Milky Way through high-quality telescopes at the Kosmos Stargazing Resort.
Just make sure to check for the latest wildfire activity before you head out.
