Black Moon is one name for the third of four new moons in a season. The August 21 new moon is the third of four new moons between the June 2017 solstice and September 2017 equinox. Voila! Black Moon eclipse.
As the moon edges toward its August 21 date with the sun, it sweeps past Venus before dawn. You can't miss the moon and Venus! They're in the east before sunup, brightest objects up there.
No matter where you live worldwide, look for the moon near the red star Aldebaran before dawn on August 16, 2017. From the Caribbean, northeastern tip of South America and North Atlantic Ocean, the moon will cover or "occult" Aldebaran.
Africa and Europe will see the partial lunar eclipse after sunset August 7. India and western Asia will see it around midnight August 7. Eastern Asia, Indonesia, Australia and New Zealand will see it before sunrise August 8.
