First Quarter in Scorpio

First Quarter on . Illuminated surface of the Moon is 48% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 2 August 2090 at 16:31 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 ♏ Scorpio

Moon is passing about ∠8° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2090 after 7 days on 10 August 2090 at 06:51.

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 ∠1938"

Lunar disc appears visually 2.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1938" and ∠1891".

Lunation 1120 / 2073

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1120 of Meeus index or 2073 from Brown series.

Synodic month length 29.32 days

The length of this lunation is 29 days, 7 hours and 40 minutes and it is 24 minutes shorter than the upcoming lunation's length. This is the year's shortest 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 shorter than mean

The length of the current synodic month is 5 hours and 4 minutes shorter than the mean synodic month length. It is 1 hour and 5 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠331.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠331.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠348.5°.

Moon after perigee

4 days since point of perigee on 28 July 2090 at 18:43 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 10 days until the Moon reaches the point of next apogee on 13 August 2090 at 08:23 in ♓ Pisces.

Distance to Moon 369 942 km

The Moon is 369 942 km (229 871 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 821 km (252 165 mi).

Moon after ascending node

3 days after ascending node on 30 July 2090 at 05:38 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 13 August 2090 at 01:17 in ♓ Pisces.

Moon before southern standstill

8 days since the last northern standstill on 24 July 2090 at 19:29 in ♊ Gemini when the Moon has reached North declination of ∠18.374° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-18.326° at the point of next southern standstill on 6 August 2090 at 13:57 in ♐ Sagittarius.

Draconic month

3 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 10 August 2090 at 06:51 in ♒ Aquarius 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.
