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 13 July 2081 at 09:34 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 about ∠23° of ♎ Libra tropical zodiac sector.
Next Full Moon is the Buck Moon of July 2081 after 7 days on 20 July 2081 at 20:22.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 3.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1946" and ∠1888".
The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1008 of Meeus index or 1961 from Brown series.
The length of this lunation is 29 days, 7 hours and 40 minutes and it is 2 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 5 hours and 4 minutes shorter than the mean synodic month length. It is 1 hour and 5 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠322.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠341.4°.
4 days since point of perigee on 9 July 2081 at 01:02 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 24 July 2081 at 19:37 in ♓ Pisces.
The Moon is 368 278 km (228 837 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 426 km (251 920 mi).
2 days after descending node on 10 July 2081 at 22:38 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 24 July 2081 at 18:52 in ♓ Pisces.
7 days since the last northern standstill on 5 July 2081 at 12:53 in ♊ Gemini when the Moon has reached North declination of ∠28.356° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-28.389° at the point of next southern standstill on 18 July 2081 at 08:57 in ♐ Sagittarius.
15 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
In 7 days on 20 July 2081 at 20:22 in ♑ Capricorn 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.
