First Quarter in Aries

First Quarter on . Illuminated surface of the Moon is 47% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 9 January 2022 at 18:11 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 ∠16° of ♈ Aries tropical zodiac sector.

Wolf Moon after 8 days

Next Full Moon is the Wolf Moon of January 2022 after 8 days on 17 January 2022 at 23:49.

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 ∠1824"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1824" and ∠1951".

Lunation 272 / 1225

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 272 of Meeus index or 1225 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 13 minutes and it is 36 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 1 hour and 32 minutes shorter than the mean synodic month length. It is 4 hours and 38 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠13.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠13.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠32°.

Moon before apogee

7 days since point of perigee on 1 January 2022 at 23:00 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 4 days until the Moon reaches the point of next apogee on 14 January 2022 at 09:27 in ♊ Gemini.

Distance to Moon 392 887 km

The Moon is 392 887 km (244 129 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 806 km (252 156 mi).

Moon before ascending node

9 days after descending node on 31 December 2021 at 01:07 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 13 January 2022 at 04:19 in ♊ Gemini.

Moon before northern standstill

6 days since the last southern standstill on 2 January 2022 at 13:35 in ♑ Capricorn when the Moon has reached South declination of ∠-26.304° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠26.310° at the point of next northern standstill on 16 January 2022 at 10:16 in ♋ Cancer.

Draconic month

23 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 8 days

In 8 days on 17 January 2022 at 23:49 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.
