Waning Crescent in Aries

Waning Crescent on . The illuminated surface of the moon is 18% and getting smaller. The lunar cycle is 25 days old.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠23° of ♈ Aries tropical zodiac sector.

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 30 May 2100 at 19:35.

Strawberry Moon after 18 days

Next Full Moon is the Strawberry Moon of June 2100 after 18 days on 22 June 2100 at 01:11.

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 ∠1768"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1891".

Lunation 1241 / 2194

The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 1241 of Meeus index or 2194 from Brown series.

Synodic month length 29.61 days

The length of this lunation is 29 days, 14 hours and 38 minutes and it is 2 hours and 3 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 1 hour and 54 minutes longer than the mean synodic month length. It is 5 hours and 9 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠200.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠200.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠227.5°.

Moon at apogee

Moon is at apogee at 17:09 about 12 days since last perigee on 22 May 2100 at 11:04 in ♏ Scorpio the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 16 days until point of next perigee on 19 June 2100 at 12:17 in ♏ Scorpio.

Distance to Moon 405 537 km

This apogee Moon is 405 537 km (251 989 mi) away from Earth. It is 129 km further than the mean apogee distance, but it is still 1 172 km closer than the farthest apogee of 21st century.

Moon after ascending node

3 days after ascending node on 31 May 2100 at 02:55 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 14 June 2100 at 11:14 in ♍ Virgo.

Moon before northern standstill

9 days since the last southern standstill on 25 May 2100 at 09:50 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.230° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠28.177° at the point of next northern standstill on 8 June 2100 at 18:51 in ♊ Gemini.

Draconic month

3 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 4 days

In 4 days on 7 June 2100 at 23:31 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.
