Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 18 May 2019 at 21:11.

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 ♑ Capricorn

Moon is passing first ∠2° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1820"

Lunar disc appears visually 4.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1820" and ∠1896".

Flower Moon before 2 days

Next Full Moon is the Strawberry Moon of June 2019 after 26 days on 17 June 2019 at 08:31.

Upcoming main Moon phases

  • Last Quarter in Aquarius ♒ on 26 May 2019 at 16:33

  • Full Moon in Sagittarius ♐ on 17 June 2019 at 08:31

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 239 / 1192

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 239 of Meeus index or 1192 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.47 days

The length of the lunation is 29 days, 11 hours and 16 minutes. It is 2 hours and 2 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 28 minutes shorter than the mean synodic month length. It is 4 hours and 41 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠263°

At the beginning of the lunation cycle the true anomaly is ∠263°. At the beginning of next synodic month the true anomaly is going to be ∠296.1°.

Moon before perigee

7 days after point of perigee on 13 May 2019 at 21:53 in ♍ Virgo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next apogee on 26 May 2019 at 13:27 in ♒ Aquarius.

Distance to Moon 393 847 km

The Moon is 393 847 km (244 725 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 404 134 km (251 117 mi).

Moon before descending node

11 days after ascending node on 9 May 2019 at 18:50 in ♋ Cancer. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 22 May 2019 at 19:12 in ♑ Capricorn.

Previous nodeNext node

Draconic month

11 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 before southern standstill

12 days since the previous standstill on 9 May 2019 at 05:46 in ♋ Cancer when the Moon has reached North declination of ∠22.243°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-22.313° at the point of next southern standstill on 22 May 2019 at 06:41 in ♑ Capricorn.

Syzygy in 12 days

In 12 days on 3 June 2019 at 10:02 in ♊ Gemini 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.
