Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♉ Taurus

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

Apparent angular diameter ∠1771"

Lunar disc appears visually 9.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1941".

Snow Moon after 7 days

Next Full Moon is the Snow Moon of February 2021 after 7 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 261 / 1214

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 261 of Meeus index or 1214 from Brown series.

Synodic month length 29.64 days

The length of the lunation is 29 days, 15 hours and 15 minutes. It is 55 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 2 hours and 31 minutes longer than the mean synodic month length. It is 4 hours and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠87°

At the beginning of the lunation cycle the true anomaly is ∠87°. At the beginning of next synodic month the true anomaly is going to be ∠124.3°.

Moon after apogee

1 day after point of apogee on 18 February 2021 at 10:22 in ♉ Taurus. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 2 March 2021 at 05:19 in ♎ Libra.

Distance to Moon 404 790 km

The Moon is 404 790 km (251 525 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 365 422 km (227 063 mi).

Moon before ascending node

12 days after descending node on 7 February 2021 at 00:29 in ♐ Sagittarius. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 21 February 2021 at 01:44 in ♊ Gemini.

Draconic month

25 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

10 days since the previous standstill on 8 February 2021 at 15:34 in ♑ Capricorn when the Moon has reached South declination of ∠-24.953°, the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠25.056° at the point of next northern standstill on 23 February 2021 at 00:12 in ♋ Cancer.

Syzygy in 7 days

In 7 days on 27 February 2021 at 08:17 in ♍ Virgo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
