First Quarter in Aries

First Quarter on . Illuminated surface of the Moon is 55% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 19 December 2061 at 23:58 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 ∠5° of ♈ Aries tropical zodiac sector.

Cold Moon after 6 days

Next Full Moon is the Cold Moon of December 2061 after 6 days on 26 December 2061 at 16:53.

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 ∠1890"

Lunar disc appears visually 3.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1890" and ∠1951".

Lunation 766 / 1719

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 766 of Meeus index or 1719 from Brown series.

Synodic month length 29.81 days

The length of this lunation is 29 days, 19 hours and 20 minutes and it is 1 hour and 2 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2061. 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°).

Lunation length longer than mean

The length of the current synodic month is 6 hours and 36 minutes longer than the mean synodic month length. It is 27 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠176.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠176.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠201.9°.

Moon after apogee

8 days since point of apogee on 12 December 2061 at 07:27 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 18 days until the Moon reaches the point of next perigee on 8 January 2062 at 09:05 in ♐ Sagittarius.

Distance to Moon 379 322 km

The Moon is 379 322 km (235 700 mi) away from Earth and getting closer over the next 18 days until the point perigee when Earth-Moon distance is going to be 406 473 km (252 571 mi).

Moon in ascending node

Moon is in ascending node in ♈ Aries at 15:02 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 2 January 2062 at 00:30 in ♎ Libra.

Moon before northern standstill

7 days since the last southern standstill on 12 December 2061 at 21:05 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.385° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠28.396° at the point of next northern standstill on 26 December 2061 at 10:29 in ♋ Cancer.

New draconic month

At 15:02 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 6 days

In 6 days on 26 December 2061 at 16:53 in ♊ Gemini 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.
