When the Last Quarter Phase of the Moon Will Occur tonight

Astronomers revealed that the last quarter phase of the moon will occur tonight starting from 11:30 p.m. EDT (03:30 GMT) in New York City. In The Sky revealed that the moon will be visible at this time shortly after it rises. Once the moon becomes half-illuminated, it will remain visible before it falls below the horizon at about 1:46 p.m. EDT (1756 GMT) on Wednesday, Aug. 9.

Scientists also referred to the last quarter phase of the moon as the third quarter moon. It mostly occurs at the halfway point between the full-lit moon and the entirely dark new moon during the 29.5 lunar cycle. Scientists revealed that the last full moon, known as August’s Sturgeon Moon surfaced on August 1.

They said that the next new moon will occur on August 16. This new moon will mark the beginning of the new lunar cycle. The full moon often rises at Sunset and sets at sunrise. However, the new moon follows a reversed path, making the moon rise at about the same time as the sun and also set with it. This makes the new moon remain almost invisible in the night sky.

Keep in mind that the last quarter phase of the moon is not the only time the moon becomes half-illuminated in the 29.5-day lunar phase. Scientists revealed that there is an analog to the last quarter moon that falls between the new moon and the full moon known as the first quarter moon. When the first quarter moon occurs, the opposite side of the moon’s surface becomes visible. Hence, the side of the moon skywatchers observes to be illuminating highly depending on the hemisphere of the region of Earth where they watch from.
