First Quarter in Libra

First Quarter on . Illuminated surface of the Moon is 60% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 25 June 2042 at 11:29 UTC.

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠16° of ♎ Libra tropical zodiac sector.

Buck Moon after 6 days

Next Full Moon is the Buck Moon of July 2042 after 6 days on 3 July 2042 at 08:09.

Neap tide

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.

Apparent angular diameter ∠1768"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1887".

Lunation 525 / 1478

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 525 of Meeus index or 1478 from Brown series.

Synodic month length 29.42 days

The length of this lunation is 29 days, 10 hours and 4 minutes and it is 2 hours and 5 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 40 minutes shorter than the mean synodic month length. It is 3 hours and 29 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠57.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠57.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠88.8°.

Moon at apogee

Moon is at apogee at 01:31 about 12 days since last perigee on 13 June 2042 at 22:24 in ♈ Aries the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 9 July 2042 at 07:47 in ♈ Aries.

Distance to Moon 404 088 km

This apogee Moon is 404 088 km (251 089 mi) away from Earth. This is the year's closest apogee of 2042. It is 1 320 km further than the mean apogee distance, but it is still 37 km closer than the farthest apogee of 21st century.

Moon before descending node

12 days after ascending node on 13 June 2042 at 12:16 in ♈ Aries the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 27 June 2042 at 04:23 in ♎ Libra.

Moon before southern standstill

8 days since the last northern standstill on 18 June 2042 at 08:35 in ♋ Cancer when the Moon has reached North declination of ∠28.070° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-28.069° at the point of next southern standstill on 2 July 2042 at 18:24 in ♐ Sagittarius.

Draconic month

12 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 3 July 2042 at 08:09 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.
