First Quarter in Virgo

First Quarter on . Illuminated surface of the Moon is 62% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 6 May 2033 at 06:45 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 is entering ♍ Virgo

Moon is passing first ∠1° of ♍ Virgo tropical zodiac sector.

Flower Moon after 6 days

Next Full Moon is the Flower Moon of May 2033 after 6 days on 14 May 2033 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 ∠1781"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1781" and ∠1901".

Lunation 412 / 1365

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 412 of Meeus index or 1365 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 50 minutes and it is 40 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2033. 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 3 hours and 54 minutes shorter than the mean synodic month length. It is 2 hours and 15 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠25.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠25.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠46°.

Moon before apogee

9 days since point of perigee on 27 April 2033 at 14:44 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 9 May 2033 at 16:25 in ♍ Virgo.

Distance to Moon 402 479 km

The Moon is 402 479 km (250 089 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 405 167 km (251 759 mi).

Moon before ascending node

9 days after descending node on 27 April 2033 at 21:57 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 11 May 2033 at 17:56 in ♎ Libra.

Moon after northern standstill

5 days since the last northern standstill on 2 May 2033 at 06:31 in ♊ Gemini when the Moon has reached North declination of ∠18.619° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-18.668° at the point of next southern standstill on 16 May 2033 at 20:25 in ♐ Sagittarius.

Draconic month

23 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 6 days

In 6 days on 14 May 2033 at 10:43 in ♏ Scorpio 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.
