The moon will be almost exactly half illuminated by the sun on Sunday (Oct. 2), during a phase called the first quarter. This will also mark the closest the moon is to Earth during its first quarter phases of 2022.
During this close first quarter moon, the moon will be about 229,985 miles (370,125 kilometers) from Earth. Following Oct. 2, the next first quarter moon happens on Nov. 1.
On Sunday, from New York City the moon will become visible at around 6:53 p.m. EDT (2253 GMT) 21 degrees above the horizon to the south. The moon will by high in the sky at around sunset and it will itself set around midnight.

The moon takes approximately 29.5 days to orbit Earth meaning that its cycle lasts around four weeks and a first quarter moon happens around once a month.
The name "first quarter" may initially sound confusing as the moon is half illuminated, but what the term actually refers to is the fact that it is a quarter of the way through its 29.5-day cycle. Which half of the moon a sky watcher sees lit during this phase of the moon depends on where they are on Earth.
Leading up to the first quarter the moon will set later every day and will be visible for longer into the night. While at the first quarter phase the moon rises around noon and sets around midnight. This means that it is high in the sky in the evening during the first quarter moon making it great for viewing.

By the time the moon reaches the full moon phase of its cycle, it will be visible for most of the night. Heading towards the full moon phase more and more of the moon's face becomes lit by the sun with the progression of light across the disk called "waxing." After the first quarter, the next major moon phase is the waxing gibbous moon which leads to the full moon.
The first quarter falls exactly between the new moon — when the moon appears almost invisible and its face is totally dark as seen from Earth — and the full moon when it appears fully illuminated.(opens in new tab)
Following the full moon, the light side of the moon will recede — a progression called waning — heading towards the third quarter moon at which point its faces will be almost exactly 50% illuminated again. This leads to the new moon and the start of a new lunar cycle.
Because the moon's orbit around Earth is a slightly flattened or elliptical circle, sometimes it is at its closest to our planet — its perigee — and sometimes it is at its furthest — its apogee.
A supermoon is when the perigee occurs during a full moon or a new moon while a full moon or new moon that falls around the apogee is called a micromoon.
