Waning Crescent in Aries

Waning Crescent on . Illuminated surface of the Moon is 21% and getting smaller. Lunar cycle is 25 days old.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠21° of ♈ Aries tropical zodiac sector.

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 2 June 2021 at 07:24.

Strawberry Moon after 19 days

Next Full Moon is the Strawberry Moon of June 2021 after 19 days on 24 June 2021 at 18:40.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1785"

Lunar disc appears visually 5.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1785" and ∠1891".

Lunation 264 / 1217

The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 264 of Meeus index or 1217 from Brown series.

Synodic month length 29.66 days

The length of this lunation is 29 days, 15 hours and 53 minutes and it is 1 hour and 29 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 3 hours and 9 minutes longer than the mean synodic month length. It is 3 hours and 54 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠178.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠178.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠202.3°.

Moon before apogee

10 days since point of perigee on 26 May 2021 at 01:52 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 8 June 2021 at 02:27 in ♉ Taurus.

Distance to Moon 401 606 km

The Moon is 401 606 km (249 546 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 406 230 km (252 420 mi).

Moon before ascending node

9 days after descending node on 26 May 2021 at 19:38 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 9 June 2021 at 16:42 in ♊ Gemini.

Moon before northern standstill

7 days since the last southern standstill on 28 May 2021 at 19:21 in ♑ Capricorn when the Moon has reached South declination of ∠-25.647° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠25.640° at the point of next northern standstill on 12 June 2021 at 04:11 in ♋ Cancer.

Draconic month

23 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 4 days

In 4 days on 10 June 2021 at 10:53 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.
