First Quarter in Virgo

First Quarter on . The illuminated surface of the moon is 54% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 17 May 2070 at 02:30 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 is entering ♍ Virgo

Moon is passing first ∠2° of ♍ Virgo tropical zodiac sector.

Flower Moon after 7 days

Next Full Moon is the Flower Moon of May 2070 after 7 days on 25 May 2070 at 01:37.

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 ∠1880"

Lunar disc appears visually 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1897".

Lunation 870 / 1823

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 870 of Meeus index or 1823 from Brown series.

Synodic month length 29.3 days

The length of this lunation is 29 days, 7 hours and 16 minutes and it is 26 minutes longer 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 5 hours and 28 minutes shorter than the mean synodic month length. It is 41 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠350.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠350.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠5.3°.

Moon after perigee

6 days since point of perigee on 11 May 2070 at 01:00 in ♉ Taurus the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 25 May 2070 at 10:55 in ♐ Sagittarius.

Distance to Moon 381 252 km

The Moon is 381 252 km (236 899 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 329 km (252 481 mi).

Moon before ascending node

8 days after descending node on 8 May 2070 at 19:39 in ♈ Aries the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 21 May 2070 at 18:54 in ♎ Libra.

Moon after northern standstill

4 days since the last northern standstill on 12 May 2070 at 15:52 in ♊ Gemini when the Moon has reached North declination of ∠18.793° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-18.834° at the point of next southern standstill on 26 May 2070 at 17:02 in ♐ Sagittarius.

Draconic month

22 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 25 May 2070 at 01:37 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.
