Moon phase and lunation details
5 days after Full Moon
Previous main lunar phase is the Full Moon before 5 days on 20 September 2021 at 23:55.
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 passing about ∠6° of ♊ Gemini tropical zodiac sector.
Apparent angular diameter ∠1768"
Lunar disc appears visually 8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1914".
Harvest Moon before 5 days
Next Full Moon is the Hunter Moon of October 2021 after 24 days on 20 October 2021 at 14:57.
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 20 days old. Earth's natural satellite is moving from the middle to the last 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 at apogee
Moon is at apogee at 21:44. It is 15 days after previous perigee on 11 September 2021 at 10:05 in ♏ Scorpio. 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 8 October 2021 at 17:28 in ♏ Scorpio.
Distance to Moon 404 641 km
This apogee Moon is 404 641 km (251 432 mi) away from Earth. It is 767 km further than the mean apogee distance, but it is still 2 068 km closer than the farthest apogee of 21st century.
Moon in ascending node
Moon is in ascending node in ♊ Gemini at 07:33 crossing the ecliptic from South to North to meet descending node 13 days later on 9 October 2021 at 19:35 in ♏ Scorpio.
New draconic month
At 07:33 the Moon completes the previous draconic month and enters the new one.
Moon before northern standstill
11 days since the previous standstill on 15 September 2021 at 03:48 in ♑ Capricorn when the Moon has reached South declination of ∠-25.980°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠26.109° at the point of next northern standstill on 29 September 2021 at 08:26 in ♋ Cancer.
Syzygy in 9 days
In 9 days on 6 October 2021 at 11:05 in ♎ Libra 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.
