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 ♏ Scorpio

Moon is leaving the last ∠2° of ♏ Scorpio tropical zodiac sector and will enter ♐ Sagittarius later.

Lunar disc appears visually 5.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1806" and ∠1904".

Pink Moon before 1 day

Lunation 226 / 1179

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 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 perigee

10 days after point of perigee on 20 April 2018 at 14:44 in ♊ Gemini. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next apogee on 6 May 2018 at 00:35 in ♑ Capricorn.

Distance to Moon 396 829 km

The Moon is 396 829 km (246 578 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 404 458 km (251 319 mi).

Moon before descending node

7 days after ascending node on 23 April 2018 at 12:19 in ♌ Leo. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 7 May 2018 at 10:24 in ♒ Aquarius.

Draconic month

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

Moon before southern standstill

10 days since the previous standstill on 21 April 2018 at 07:38 in ♋ Cancer when the Moon has reached North declination of ∠20.445°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-20.562° at the point of next southern standstill on 4 May 2018 at 23:00 in ♑ Capricorn.

Syzygy in 13 days

In 13 days 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.
