Last Quarter in Sagittarius

Last Quarter on . Illuminated surface of the Moon is 48% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 21 February 2090 at 07:42 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 ♐ Sagittarius

Moon is passing about ∠5° of ♐ Sagittarius tropical zodiac sector.

Worm Moon after 22 days

Next Full Moon is the Worm Moon of March 2090 after 22 days on 15 March 2090 at 23:42.

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 ∠1863"

Lunar disc appears visually 4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1863" and ∠1940".

Lunation 1114 / 2067

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 1114 of Meeus index or 2067 from Brown series.

Synodic month length 29.8 days

The length of this lunation is 29 days, 19 hours and 12 minutes and it is 1 hour and 10 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2090. 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 6 hours and 28 minutes longer than the mean synodic month length. It is 35 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠163.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠163.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠188.4°.

Moon after perigee

6 days since point of perigee on 14 February 2090 at 17:13 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 28 February 2090 at 10:33 in ♒ Aquarius.

Distance to Moon 384 678 km

The Moon is 384 678 km (239 028 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 559 km (252 624 mi).

Moon after ascending node

4 days after ascending node on 16 February 2090 at 19:19 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 2 March 2090 at 23:32 in ♓ Pisces.

Moon before southern standstill

10 days since the last northern standstill on 10 February 2090 at 19:04 in ♊ Gemini when the Moon has reached North declination of ∠18.250° the lunar orbit is extending southward over the next day to face maximum declination of ∠-18.192° at the point of next southern standstill on 23 February 2090 at 11:00 in ♑ Capricorn.

Draconic month

4 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 1 March 2090 at 09:46 in ♓ Pisces 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.
