Moon phase and lunation details

1 day after First Quarter

Previous main lunar phase is the First Quarter before 1 day on 13 September 2021 at 20:39.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♑ Capricorn

Moon is passing about ∠14° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1951"

Lunar disc appears visually 2.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1951" and ∠1908".

Harvest Moon after 5 days

Next Full Moon is the Harvest Moon of September 2021 after 5 days on 20 September 2021 at 23:55.

Upcoming main Moon phases

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.

Lunation 268 / 1221

The Moon is 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 268 of Meeus index or 1221 from Brown series.

Synodic month length 29.43 days

The length of the lunation is 29 days, 10 hours and 14 minutes. It is 5 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 30 minutes shorter than the mean synodic month length. It is 3 hours and 39 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠297.8°

At the beginning of the lunation cycle the true anomaly is ∠297.8°. At the beginning of next synodic month the true anomaly is going to be ∠323.3°.

Moon after perigee

4 days after point of perigee on 11 September 2021 at 10:05 in ♏ Scorpio. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 367 412 km

The Moon is 367 412 km (228 299 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 404 641 km (251 432 mi).

Moon after descending node

2 days after descending node on 12 September 2021 at 16:35 in ♏ Scorpio. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 26 September 2021 at 07:33 in ♊ Gemini.

Draconic month

16 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the second to the final part of the cycle.

Moon at southern standstill

At 03:48 the Moon is meeting its standstill point to reach South declination of ∠-25.980°. Over the next 13 days the lunar orbit is going to extend northward to face maximum declination of ∠26.109° at the point of next standstill in ♋ Cancer on 29 September 2021 at 08:26.

Syzygy in 5 days

In 5 days on 20 September 2021 at 23:55 in ♓ Pisces 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.
