Last Quarter in Taurus

Last Quarter on . Illuminated surface of the Moon is 44% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 11 August 2039 at 19:36 UTC.

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♉ Taurus

Moon is leaving the last ∠3° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Harvest Moon after 21 days

Next Full Moon is the Harvest Moon of September 2039 after 21 days on 2 September 2039 at 19:23.

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 ∠1772"

Lunar disc appears visually 6.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1894".

Lunation 489 / 1442

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 489 of Meeus index or 1442 from Brown series.

Synodic month length 29.54 days

The length of this lunation is 29 days, 12 hours and 56 minutes and it is 1 hour and 24 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 12 minutes longer than the mean synodic month length. It is 6 hours and 51 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠226.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠226.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠260.1°.

Moon before apogee

10 days since point of perigee on 1 August 2039 at 22:38 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 13 August 2039 at 19:35 in ♊ Gemini.

Distance to Moon 404 403 km

The Moon is 404 403 km (251 284 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 503 km (251 347 mi).

Moon before ascending node

11 days after descending node on 31 July 2039 at 22:26 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 14 August 2039 at 10:57 in ♊ Gemini.

Moon before northern standstill

10 days since the last southern standstill on 2 August 2039 at 07:15 in ♑ Capricorn when the Moon has reached South declination of ∠-24.732° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠24.786° at the point of next northern standstill on 16 August 2039 at 04:38 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 19 August 2039 at 20:50 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.
