First Quarter in Virgo

First Quarter on . Illuminated surface of the Moon is 60% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 1 June 2017 at 12:42 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 ♍ Virgo

Moon is passing about ∠24° of ♍ Virgo tropical zodiac sector.

Strawberry Moon after 7 days

Next Full Moon is the Strawberry Moon of June 2017 after 7 days on 9 June 2017 at 13:10.

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 ∠1850"

Lunar disc appears visually 2.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1850" and ∠1892".

Lunation 215 / 1168

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 215 of Meeus index or 1168 from Brown series.

Synodic month length 29.28 days

The length of this lunation is 29 days, 6 hours and 46 minutes and it is 29 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2017. 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 5 hours and 58 minutes shorter than the mean synodic month length. It is 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠356°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠356° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠11°.

Moon before apogee

7 days since point of perigee on 26 May 2017 at 01:23 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 8 June 2017 at 22:21 in ♐ Sagittarius.

Distance to Moon 387 551 km

The Moon is 387 551 km (240 813 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 402 km (252 526 mi).

Moon after ascending node

2 days after ascending node on 31 May 2017 at 11:56 in ♌ Leo the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 15 June 2017 at 02:40 in ♒ Aquarius.

Moon after northern standstill

5 days since the last northern standstill on 27 May 2017 at 23:36 in ♋ Cancer when the Moon has reached North declination of ∠19.362° the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-19.428° at the point of next southern standstill on 11 June 2017 at 03:36 in ♑ Capricorn.

Draconic month

2 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 9 June 2017 at 13:10 in ♐ Sagittarius 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.
