First Quarter in Aries

First Quarter on . Illuminated surface of the Moon is 49% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 16 January 2092 at 14:08 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 ♈ Aries

Moon is passing about ∠25° of ♈ Aries tropical zodiac sector.

Wolf Moon after 8 days

Next Full Moon is the Wolf Moon of January 2092 after 8 days on 24 January 2092 at 14:55.

Moderate tide

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.

Apparent angular diameter ∠1776"

Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1950".

Lunation 1138 / 2091

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1138 of Meeus index or 2091 from Brown series.

Synodic month length 29.56 days

The length of this lunation is 29 days, 13 hours and 26 minutes and it is 1 hour and 28 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 longer than mean

The length of the current synodic month is 42 minutes longer than the mean synodic month length. It is 6 hours and 21 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠40.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠40.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠69.4°.

Moon before apogee

9 days since point of perigee on 6 January 2092 at 12:22 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 18 January 2092 at 05:57 in ♉ Taurus.

Distance to Moon 403 623 km

The Moon is 403 623 km (250 800 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 702 km (251 470 mi).

Moon after descending node

4 days after descending node on 11 January 2092 at 13:52 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 January 2092 at 01:05 in ♌ Leo.

Moon before northern standstill

8 days since the last southern standstill on 8 January 2092 at 08:40 in ♑ Capricorn when the Moon has reached South declination of ∠-19.466° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠19.448° at the point of next northern standstill on 22 January 2092 at 14:14 in ♋ Cancer.

Draconic month

17 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 24 January 2092 at 14:55 in ♋ Cancer 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.
