First Quarter in Scorpio

First Quarter on . Illuminated surface of the Moon is 63% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 24 July 2015 at 04:04 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 ∠17° of ♏ Scorpio tropical zodiac sector.

Buck Moon after 5 days

Next Full Moon is the Buck Moon of July 2015 after 5 days on 31 July 2015 at 10:43.

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 ∠1806"

Lunar disc appears visually 4.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1806" and ∠1889".

Lunation 192 / 1145

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 192 of Meeus index or 1145 from Brown series.

Synodic month length 29.56 days

The length of this lunation is 29 days, 13 hours and 29 minutes and it is 2 hours and 19 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 longer than mean

The length of the current synodic month is 45 minutes longer than the mean synodic month length. It is 6 hours and 18 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠112.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠112.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠144.1°.

Moon after apogee

4 days since point of apogee on 21 July 2015 at 11:02 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 2 August 2015 at 10:11 in ♓ Pisces.

Distance to Moon 396 953 km

The Moon is 396 953 km (246 655 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 362 135 km (225 020 mi).

Moon after ascending node

3 days after ascending node on 21 July 2015 at 19:32 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 4 August 2015 at 02:53 in ♈ Aries.

Moon before southern standstill

11 days since the last northern standstill on 14 July 2015 at 04:24 in ♊ Gemini when the Moon has reached North declination of ∠18.417° the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-18.344° at the point of next southern standstill on 28 July 2015 at 17:34 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 5 days

In 5 days on 31 July 2015 at 10:43 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.
