Waning Crescent in Taurus

Waning Crescent on . Illuminated surface of the Moon is 41% and getting smaller. Lunar cycle is 23 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 ♉ Taurus

Moon is passing about ∠20° of ♉ Taurus tropical zodiac sector.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 31 July 2021 at 13:16.

Sturgeon Moon after 21 days

Next Full Moon is the Sturgeon Moon of August 2021 after 21 days on 22 August 2021 at 12:02.

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 ∠1770"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1891".

Lunation 266 / 1219

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 266 of Meeus index or 1219 from Brown series.

Synodic month length 29.52 days

The length of this lunation is 29 days, 12 hours and 34 minutes and it is 1 hour and 32 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 shorter than mean

The length of the current synodic month is 11 minutes shorter than the mean synodic month length. It is 5 hours and 59 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠230.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠230.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠264.3°.

Moon before apogee

11 days since point of perigee on 21 July 2021 at 10:30 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 2 August 2021 at 07:35 in ♉ Taurus.

Distance to Moon 405 040 km

The Moon is 405 040 km (251 680 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 412 km (251 290 mi).

Moon before ascending node

11 days after descending node on 20 July 2021 at 13:22 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 3 August 2021 at 02:51 in ♊ Gemini.

Moon before northern standstill

9 days since the last southern standstill on 22 July 2021 at 15:11 in ♑ Capricorn when the Moon has reached South declination of ∠-25.643° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠25.685° at the point of next northern standstill on 5 August 2021 at 16:46 in ♋ Cancer.

Draconic month

25 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 7 days

In 7 days on 8 August 2021 at 13:50 in ♌ Leo 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.
