Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 18 October 2100 at 04:06.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♊ Gemini

Moon is leaving the last ∠2° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Apparent angular diameter ∠1795"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1795" and ∠1929".

Hunter Moon before 5 days

Next Full Moon is the Beaver Moon of November 2100 after 24 days on 16 November 2100 at 22:19.

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 1246 / 2199

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 1246 of Meeus index or 2199 from Brown series.

Synodic month length 29.38 days

The length of the lunation is 29 days, 9 hours and 12 minutes. This is the year's shortest synodic month of 2100. It is 34 minutes shorter 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 3 hours and 32 minutes shorter than the mean synodic month length. It is 2 hours and 37 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠340.4°

At the beginning of the lunation cycle the true anomaly is ∠340.4°. At the beginning of next synodic month the true anomaly is going to be ∠356.4°.

Moon after apogee

3 days after point of apogee on 20 October 2100 at 04:03 in ♉ Taurus. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 2 November 2100 at 08:19 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 399 371 km

The Moon is 399 371 km (248 158 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 356 834 km (221 726 mi).

Moon before descending node

9 days after ascending node on 14 October 2100 at 06:36 in ♓ Pisces. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 28 October 2100 at 20:12 in ♌ Leo.

Draconic month

9 days since the beginning of current draconic month in ♓ Pisces, the Moon is navigating from the beginning to the first part of the cycle.

Moon at northern standstill

At 08:12 the Moon is meeting its standstill point to reach North declination of ∠28.129°. Over the next 12 days the lunar orbit is going to extend southward to face maximum declination of ∠-28.051° at the point of next standstill in ♐ Sagittarius on 5 November 2100 at 05:15.

Syzygy in 9 days

In 9 days on 2 November 2100 at 03:14 in ♏ Scorpio the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
