Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 5 May 2023 at 17:34.

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 ♒ Aquarius

Moon is passing about ∠6° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 3.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1900".

Flower Moon before 5 days

Next Full Moon is the Strawberry Moon of June 2023 after 23 days on 4 June 2023 at 03:42.

Upcoming main Moon phases

  • Last Quarter in Aquarius ♒ on 12 May 2023 at 14:28
  • New Moon in Taurus ♉ on 19 May 2023 at 15:53

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 288 / 1241

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 288 of Meeus index or 1241 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.49 days

The length of the lunation is 29 days, 11 hours and 41 minutes. It is 1 hour and 3 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 shorter than mean

The length of the current synodic month is 1 hour and 3 minutes shorter than the mean synodic month length. It is 5 hours and 6 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠59.2°

At the beginning of the lunation cycle the true anomaly is ∠59.2°. At the beginning of next synodic month the true anomaly is going to be ∠92.6°.

Moon at perigee

Moon is at perigee at 04:57. It is 12 days after previous apogee on 28 April 2023 at 06:43 in ♌ Leo. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 14 days, until point of next apogee on 26 May 2023 at 01:39 in ♌ Leo.

Previous apogeeNext apogee

Distance to Moon 369 345 km

This perigee Moon is 369 345 km (229 500 mi) away from Earth. It is 6 837 km closer than the mean perigee distance, but it is still 1 011 km further than the closest perigee of 21st century.

Moon before ascending node

6 days after descending node on 4 May 2023 at 21:57 in ♎ Libra. The Moon is located south of the ecliptic over the following 6 days, until the lunar orbit crosses from South to North in ascending node on 17 May 2023 at 19:36 in ♈ Aries.

Previous nodeNext node

Draconic month

21 days since the beginning of current draconic month in ♉ Taurus, the Moon is navigating from the second to the final part of the cycle.

Moon after southern standstill

2 days since the previous standstill on 9 May 2023 at 09:01 in ♑ Capricorn when the Moon has reached South declination of ∠-27.937°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠27.903° at the point of next northern standstill on 22 May 2023 at 14:08 in ♊ Gemini.

Syzygy in 8 days

In 8 days on 19 May 2023 at 15:53 in ♉ Taurus 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.
