The Full Harvest Moon will brighten the night sky on Friday.
The moon becomes full at 3:05 p.m., and it rises in Baltimore at 7:21 p.m., about 10 minutes after sunset. The moon always rises around sunset when it is full, because that is when Earth is directly between it and the sun.
This month, that celestial arrangement brings a minor eclipse, but it is only visible from the eastern hemisphere. What is known as a penumbral eclipse, when the edge of Earth's shadow slightly dims the full moon, will occur from about 1 p.m. to 5 p.m. local time.
Skies are forecast to be partly cloudy in the Baltimore area.
As the moon rises, you can spot Mars and Saturn in the south-southwestern sky. In the early morning Saturday as the moon sets in the west, you might be able to spot Mercury equally low on the eastern horizon.
This month's full moon is known as the Harvest Moon because it is closest to next week's autumnal equinox. It is also known as the Full Corn Moon.
