First Quarter in Scorpio

First Quarter on . Illuminated surface of the Moon is 50% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 1 August 2025 at 12:41 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 ∠9° of ♏ Scorpio tropical zodiac sector.

Sturgeon Moon after 7 days

Next Full Moon is the Sturgeon Moon of August 2025 after 7 days on 9 August 2025 at 07:55.

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 ∠1768"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1891".

Lunation 316 / 1269

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 316 of Meeus index or 1269 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 55 minutes and it is 2 hours and 53 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 1 hour and 49 minutes shorter than the mean synodic month length. It is 4 hours and 20 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠60.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠60.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠93°.

Moon at apogee

Moon is at apogee at 20:37 about 12 days since last perigee on 20 July 2025 at 13:52 in ♉ Taurus the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 13 days until point of next perigee on 14 August 2025 at 18:01 in ♈ Aries.

Distance to Moon 404 164 km

This apogee Moon is 404 164 km (251 136 mi) away from Earth. This is the year's closest apogee of 2025. It is 1 244 km further than the mean apogee distance, but it is still 113 km closer than the farthest apogee of 21st century.

Moon after descending node

4 days after descending node on 28 July 2025 at 08:30 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 August 2025 at 14:53 in ♓ Pisces.

Moon before southern standstill

10 days since the last northern standstill on 22 July 2025 at 09:43 in ♊ Gemini when the Moon has reached North declination of ∠28.474° the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-28.534° at the point of next southern standstill on 5 August 2025 at 13:37 in ♐ Sagittarius.

Draconic month

17 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 9 August 2025 at 07:55 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.
