First Quarter in Sagittarius

First Quarter on . Illuminated surface of the Moon is 47% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 18 September 2026 at 20:44 UTC.

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♐ Sagittarius

Moon is passing about ∠22° of ♐ Sagittarius tropical zodiac sector.

Harvest Moon after 8 days

Next Full Moon is the Harvest Moon of September 2026 after 8 days on 26 September 2026 at 16:49.

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 ∠1769"

Lunar disc appears visually 7.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1910".

Lunation 330 / 1283

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 330 of Meeus index or 1283 from Brown series.

Synodic month length 29.52 days

The length of this lunation is 29 days, 12 hours and 23 minutes and it is 2 hours and 49 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 21 minutes shorter than the mean synodic month length. It is 5 hours and 48 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠61.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠61.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠94.5°.

Moon before apogee

11 days since point of perigee on 6 September 2026 at 20:26 in ♋ Cancer 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 19 September 2026 at 03:00 in ♐ Sagittarius.

Distance to Moon 405 255 km

The Moon is 405 255 km (251 814 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 217 km (251 169 mi).

Moon before ascending node

8 days after descending node on 9 September 2026 at 19:17 in ♌ Leo the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 24 September 2026 at 02:40 in ♒ Aquarius.

Moon at southern standstill

At 18:54 the Moon is meeting its standstill point to reach South declination of ∠-28.065°. Over the upcoming 13 days the lunar orbit is going to tilt northward to face maximum declination of ∠27.989° at the point of next northern standstill in ♊ Gemini on 2 October 2026 at 11:35.

Draconic month

21 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 26 September 2026 at 16:49 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
