A Black Moon supermoon will occur on Wednesday, July 31, 2019, which begins with a moonrise over the Atlantic Ocean around 6:00 a.m. Eastern Daylight Time (with plus or minus time deviation depending on where you live on the U.S. east coast).
This New Moon will be difficult to see with the human eye due to the sun’s glare. Only special photography equipment with filters will be able to view the super black moon.
However, skywatchers will be able to see the Milky Way and Perseid Meteor Shower very clearly where there is no cloud cover or artificial light pollution due to the very dark skies created by the Black Moon supermoon and the moonset around 8 p.m. Eastern Daylight Time.
Similar to a Blue Moon, a Black Moon is the second New Moon in a calendar month. New moons are separated by 29.5 days but most months are 30 or 31 days long – so it is possible to fit two new moons in a single month occasionally. This happens every two and a half years, on average.
A supermoon occurs because the moon is in an elliptical orbit around the Earth. When the moon is closest to Earth, it is at its orbital perigee, which is why a supermoon is also known as a Perigee Moon.
It is called a “Black Supermoon” because this moon is both a Black Moon and a supermoon.
This Black Moon begins with a moonrise over the Atlantic Ocean at 6 a.m. Eastern Daylight Time on March 31, 2018, which sets the following morning at 8:08 p.m. (with a few minutes of variation depending on your exact location in Florida or several minutes along the rest of the U.S. east coast).
This Black Moon will only have 0.3% illumination on July 31st.
