Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 10 May 2017 at 21:43.

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 ♐ Sagittarius

Moon is passing about ∠9° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1899".

Flower Moon before 1 day

Next Full Moon is the Strawberry Moon of June 2017 after 28 days on 9 June 2017 at 13:10.

Upcoming main Moon phases

  • Last Quarter in Pisces ♓ on 19 May 2017 at 00:33
  • New Moon in Taurus ♉ on 25 May 2017 at 19:44
  • First Quarter in Virgo ♍ on 1 June 2017 at 12:42
  • Full Moon in Sagittarius ♐ on 9 June 2017 at 13:10

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 214 / 1167

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 214 of Meeus index or 1167 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.31 days

The length of the lunation is 29 days, 7 hours and 28 minutes. It is 42 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 5 hours and 16 minutes shorter than the mean synodic month length. It is 53 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠340.4°

At the beginning of the lunation cycle the true anomaly is ∠340.4°. At the beginning of next synodic month the true anomaly is going to be ∠356°.

Moon at apogee

Moon is at apogee at 19:51. It is 15 days after previous perigee on 27 April 2017 at 16:18 in ♉ Taurus. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 13 days, until point of next perigee on 26 May 2017 at 01:23 in ♊ Gemini.

Distance to Moon 406 212 km

This apogee Moon is 406 212 km (252 408 mi) away from Earth. It is 804 km further than the mean apogee distance, but it is still 497 km closer than the farthest apogee of 21st century.

Moon before descending node

8 days after ascending node on 4 May 2017 at 10:42 in ♍ Virgo. The Moon is located north of the ecliptic over the following 6 days, until the lunar orbit crosses from North to South in descending node on 19 May 2017 at 01:30 in ♒ Aquarius.

Previous nodeNext node

Draconic month

8 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the beginning to the first part of the cycle.

Moon before southern standstill

11 days since the previous standstill on 30 April 2017 at 13:33 in ♊ Gemini when the Moon has reached North declination of ∠19.187°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-19.302° at the point of next southern standstill on 14 May 2017 at 20:29 in ♑ Capricorn.

Syzygy in 13 days

In 13 days on 25 May 2017 at 19:44 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.
