First Quarter on . The illuminated surface of the moon is 51% and growing larger. The lunar cycle is 7 days young.
* The exact date and time of this First Quarter phase is on 18 March 2081 at 09:27 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing first ∠0° of ♊ Gemini tropical zodiac sector.
Next Full Moon is the Worm Moon of March 2081 after 6 days on 25 March 2081 at 00:29.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 0.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1925" and ∠1927".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1004 of Meeus index or 1957 from Brown series.
The length of this lunation is 29 days, 16 hours and 58 minutes and it is 3 hours and 4 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 4 hours and 14 minutes longer than the mean synodic month length. It is 2 hours and 49 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠202.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠231.2°.
10 days since point of apogee on 8 March 2081 at 06:10 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 23 March 2081 at 16:38 in ♍ Virgo.
The Moon is 372 396 km (231 396 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 359 723 km (223 522 mi).
7 days after ascending node on 10 March 2081 at 22:30 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 24 March 2081 at 07:17 in ♍ Virgo.
At 10:34 the Moon is meeting its standstill point to reach North declination of ∠28.673°. This is the year's northernmost lunar standstill of 2081. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.653° at the point of next southern standstill in ♐ Sagittarius on 31 March 2081 at 02:35.
7 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 6 days on 25 March 2081 at 00:29 in ♎ Libra the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
