Moon phase and lunation details

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 8 May 2018 at 02:09.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♈ Aries

Moon is leaving the last ∠4° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.

Apparent angular diameter ∠1881"

Lunar disc appears visually 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1881" and ∠1899".

Flower Moon after 16 days

Next Full Moon is the Flower Moon of May 2018 after 16 days on 29 May 2018 at 14:20.

Lunation 226 / 1179

The Moon is 27 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 226 of Meeus index or 1179 from Brown series.

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 51 minutes. It is 1 hour and 56 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 2 hours and 53 minutes shorter than the mean synodic month length. It is 3 hours and 16 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠296.5°

At the beginning of the lunation cycle the true anomaly is ∠296.5°. At the beginning of next synodic month the true anomaly is going to be ∠321.7°.

Moon before apogee

7 days after point of apogee on 6 May 2018 at 00:35 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 17 May 2018 at 21:06 in ♊ Gemini.

Previous apogeeNext perigee

Distance to Moon 381 034 km

The Moon is 381 034 km (236 764 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 363 777 km (226 041 mi).

Moon after descending node

6 days after descending node on 7 May 2018 at 10:24 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 7 days, until the lunar orbit crosses from South to North in ascending node on 20 May 2018 at 13:13 in ♌ Leo.

Previous nodeNext node

Draconic month

19 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

8 days since the previous standstill on 4 May 2018 at 23:00 in ♑ Capricorn when the Moon has reached South declination of ∠-20.562°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠20.652° at the point of next northern standstill on 18 May 2018 at 15:02 in ♋ Cancer.

Syzygy in 1 day

In 1 day on 15 May 2018 at 11:48 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.
