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 ♌ Leo

Moon is passing about ∠22° of ♌ Leo tropical zodiac sector.

Apparent angular diameter ∠1973"

Lunar disc appears visually 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1904".

Flower Moon after 6 days

Next Full Moon is the Flower Moon of May 2001 after 6 days on 7 May 2001 at 13:53.

Upcoming main Moon phases

  • Full Moon in Scorpio ♏ on 7 May 2001 at 13:53
  • Last Quarter in Aquarius ♒ on 15 May 2001 at 10:11

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 16 / 969

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 16 of Meeus index or 969 from Brown series.

Synodic month length 29.47 days

The length of the lunation is 29 days, 11 hours and 20 minutes. It is 2 hours and 8 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 1 hour and 24 minutes shorter than the mean synodic month length. It is 4 hours and 45 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠267.3°

At the beginning of the lunation cycle the true anomaly is ∠267.3°. At the beginning of next synodic month the true anomaly is going to be ∠299.7°.

Moon before apogee

14 days after point of apogee on 17 April 2001 at 06:06 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next day, until the Moon reaches the point of next perigee on 2 May 2001 at 03:37 in ♍ Virgo.

Distance to Moon 363 345 km

The Moon is 363 345 km (225 772 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 369 426 km (229 551 mi).

Moon after ascending node

3 days after ascending node on 28 April 2001 at 09:43 in ♋ Cancer. The Moon is located north of the ecliptic over the following 9 days, until the lunar orbit crosses from North to South in descending node on 11 May 2001 at 11:02 in ♑ Capricorn.

Draconic month

3 days since the beginning of current draconic month in ♋ Cancer, the Moon is navigating from the beginning to the first part of the cycle.

Moon after northern standstill

2 days since the previous standstill on 28 April 2001 at 16:18 in ♋ Cancer when the Moon has reached North declination of ∠23.248°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-23.329° at the point of next southern standstill on 11 May 2001 at 20:26 in ♑ Capricorn.

Syzygy in 6 days

In 6 days on 7 May 2001 at 13:53 in ♏ Scorpio 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.
