Moon phase and lunation details
4 days after Full Moon
Previous main lunar phase is the Full Moon before 4 days on 20 October 2021 at 14:57.
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 ∠4° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.
Apparent angular diameter ∠1771"
Lunar disc appears visually 8.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1930".
Hunter Moon before 4 days
Next Full Moon is the Beaver Moon of November 2021 after 24 days on 19 November 2021 at 08:58.
Upcoming main Moon phases
- Last Quarter in Cancer ♋ on 28 October 2021 at 20:05
- New Moon in Scorpio ♏ on 4 November 2021 at 21:15
- First Quarter in Aquarius ♒ on 11 November 2021 at 12:46
- Full Moon in Taurus ♉ on 19 November 2021 at 08:58
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 269 / 1222
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 269 of Meeus index or 1222 from Brown series.
Synodic month length 29.42 days
The length of the lunation is 29 days, 10 hours and 9 minutes. This is the year's shortest synodic month of 2021. It is 19 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 2 hours and 35 minutes shorter than the mean synodic month length. It is 3 hours and 34 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠323.3°
At the beginning of the lunation cycle the true anomaly is ∠323.3°. At the beginning of next synodic month the true anomaly is going to be ∠342.3°.
Moon after apogee
1 day after point of apogee on 24 October 2021 at 15:30 in ♊ Gemini. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next perigee on 5 November 2021 at 22:23 in ♏ Scorpio.
Distance to Moon 404 773 km
The Moon is 404 773 km (251 514 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 358 845 km (222 976 mi).
Moon after ascending node
2 days after ascending node on 23 October 2021 at 11:47 in ♊ Gemini. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 6 November 2021 at 03:38 in ♐ Sagittarius.
Draconic month
2 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the beginning to the first part of the cycle.
Moon before northern standstill
13 days since the previous standstill on 12 October 2021 at 09:09 in ♑ Capricorn when the Moon has reached South declination of ∠-26.204°, the lunar orbit is extending northward over the next day to face maximum declination of ∠26.291° at the point of next northern standstill on 26 October 2021 at 16:04 in ♋ Cancer.
Syzygy in 10 days
In 10 days on 4 November 2021 at 21:15 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.
