Waxing Gibbous in Virgo

Waxing Gibbous on . Illuminated surface of the Moon is 68% and growing larger. Lunar cycle is 9 days young.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♍ Virgo

Moon is passing about ∠13° of ♍ Virgo tropical zodiac sector.

1 day after First Quarter

Previous main lunar phase is the First Quarter before 1 day on 10 May 2011 at 20:33.

Flower Moon after 4 days

Next Full Moon is the Flower Moon of May 2011 after 4 days on 17 May 2011 at 11:09.

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 ∠1965"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1965" and ∠1899".

Lunation 140 / 1093

The Moon is 9 days young and navigating from the first to the middle part of the current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 12 minutes and it is 2 hours and 21 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 28 minutes longer than the mean synodic month length. It is 5 hours and 35 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠216.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠216.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠248.4°.

Moon before perigee

12 days since point of apogee on 29 April 2011 at 18:02 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 15 May 2011 at 11:18 in ♎ Libra.

Distance to Moon 364 702 km

The Moon is 364 702 km (226 615 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 362 133 km (225 019 mi).

Moon after descending node

5 days after descending node on 6 May 2011 at 14:54 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius.

Moon after northern standstill

6 days since the last northern standstill on 6 May 2011 at 03:54 in ♊ Gemini when the Moon has reached North declination of ∠23.421° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-23.403° at the point of next southern standstill on 18 May 2011 at 23:26 in ♐ Sagittarius.

Draconic month

20 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 4 days

In 4 days on 17 May 2011 at 11:09 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.
