Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 28 January 2021 at 19:16.

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 is entering ♍ Virgo

Moon is passing first ∠2° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1907"

Lunar disc appears visually 2.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1907" and ∠1948".

Wolf Moon before 1 day

Next Full Moon is the Snow Moon of February 2021 after 27 days on 27 February 2021 at 08:17.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 260 / 1213

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 260 of Meeus index or 1213 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.59 days

The length of the lunation is 29 days, 14 hours and 5 minutes. It is 1 hour and 10 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 21 minutes longer than the mean synodic month length. It is 5 hours and 42 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠53.8°

At the beginning of the lunation cycle the true anomaly is ∠53.8°. At the beginning of next synodic month the true anomaly is going to be ∠87°.

Moon before apogee

8 days after point of apogee on 21 January 2021 at 13:11 in ♉ Taurus. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 3 February 2021 at 19:33 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 375 962 km

The Moon is 375 962 km (233 612 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 370 127 km (229 986 mi).

Moon after ascending node

5 days after ascending node on 24 January 2021 at 21:47 in ♊ Gemini. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 7 February 2021 at 00:29 in ♐ Sagittarius.

Draconic month

5 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 after northern standstill

3 days since the previous standstill on 26 January 2021 at 15:39 in ♋ Cancer when the Moon has reached North declination of ∠24.898°, the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-24.953° at the point of next southern standstill on 8 February 2021 at 15:34 in ♑ Capricorn.

Syzygy in 12 days

In 12 days on 11 February 2021 at 19:06 in ♒ Aquarius 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.
