First Quarter in Sagittarius

First Quarter on . The illuminated surface of the moon is 53% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 15 September 2048 at 06:04 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♐ Sagittarius

Moon is leaving the last ∠3° of ♐ Sagittarius tropical zodiac sector and will enter ♑ Capricorn later.

Harvest Moon after 6 days

Next Full Moon is the Harvest Moon of September 2048 after 6 days on 22 September 2048 at 04:46.

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 ∠1973"

Lunar disc appears visually 3.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1909".

Lunation 602 / 1555

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 602 of Meeus index or 1555 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 21 minutes and it is 28 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 1 hour and 23 minutes shorter than the mean synodic month length. It is 4 hours and 46 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠276°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠276° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠307.5°.

Moon at perigee

Moon is at perigee at 15:06 about 14 days since last apogee on 1 September 2048 at 10:48 in ♊ Gemini the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 13 days until point of next apogee on 29 September 2048 at 06:20 in ♊ Gemini.

Distance to Moon 369 916 km

This perigee Moon is 369 916 km (229 855 mi) away from Earth. This is the year's farthest perigee of 2048. It is 7 408 km closer than the mean perigee distance, but it is still 440 km further than the closest perigee of 21st century.

Moon in ascending node

Moon is in ascending node in ♐ Sagittarius at 06:06 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 28 September 2048 at 18:16 in ♊ Gemini.

Moon after southern standstill

1 day since the last southern standstill on 14 September 2048 at 22:20 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.317° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠23.189° at the point of next northern standstill on 28 September 2048 at 11:46 in ♊ Gemini.

New draconic month

At 06:06 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 6 days

In 6 days on 22 September 2048 at 04:46 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.
