Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 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 ♉ Taurus

Moon is passing about ∠23° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1927".

Hunter Moon before 2 days

Next Full Moon is the Beaver Moon of November 2100 after 27 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 17 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 at apogee

Moon is at apogee at 04:03. It is 15 days after previous perigee on 4 October 2100 at 21:58 in ♎ Libra. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 12 days, until point of next perigee on 2 November 2100 at 08:19 in ♏ Scorpio.

Distance to Moon 406 359 km

This apogee Moon is 406 359 km (252 500 mi) away from Earth. It is 951 km further than the mean apogee distance, but it is still 350 km closer than the farthest apogee of 21st century.

Moon after ascending node

6 days after ascending node on 14 October 2100 at 06:36 in ♓ Pisces. The Moon is located north of the ecliptic over the following 8 days, until the lunar orbit crosses from North to South in descending node on 28 October 2100 at 20:12 in ♌ Leo.

Draconic month

6 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 before northern standstill

11 days since the previous standstill on 8 October 2100 at 20:58 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.233°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠28.129° at the point of next northern standstill on 23 October 2100 at 08:12 in ♊ Gemini.

Syzygy in 12 days

In 12 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.
