First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 61% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 2 January 2039 at 07:37 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♈ Aries

Moon is leaving the last ∠4° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2039 after 6 days on 10 January 2039 at 11:45.

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 ∠1777"

Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1777" and ∠1951".

Lunation 482 / 1435

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 482 of Meeus index or 1435 from Brown series.

Synodic month length 29.52 days

The length of this lunation is 29 days, 12 hours and 34 minutes and it is 1 hour and 7 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 10 minutes shorter than the mean synodic month length. It is 5 hours and 59 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠28.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠28.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠51.2°.

Moon before apogee

10 days since point of perigee on 24 December 2038 at 08:23 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 5 January 2039 at 05:10 in ♉ Taurus.

Distance to Moon 403 430 km

The Moon is 403 430 km (250 680 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 107 km (251 722 mi).

Moon before ascending node

8 days after descending node on 25 December 2038 at 19:56 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 8 January 2039 at 23:18 in ♊ Gemini.

Moon before northern standstill

7 days since the last southern standstill on 26 December 2038 at 13:42 in ♑ Capricorn when the Moon has reached South declination of ∠-23.882° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠23.878° at the point of next northern standstill on 9 January 2039 at 20:11 in ♋ Cancer.

Draconic month

21 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 10 January 2039 at 11:45 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.
