Full Moon in Virgo

Full Moon on . Illuminated surface of the Moon is 100%. Lunar cycle is 15 days old.

* The exact date and time of this Full Moon phase is on 18 February 2011 at 08:36 UTC.

Moonrise and moonset

Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

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.

It is Snow Moon

The Full Moon these days is the Snow of February 2011.

Spring tide

There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

Apparent angular diameter ∠1963"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1963" and ∠1941".

Lunation 137 / 1090

The Moon is 15 days old and navigating through the middle part of the current synodic month. This is lunation 137 of Meeus index or 1090 from Brown series.

Synodic month length 29.76 days

The length of this lunation is 29 days, 18 hours and 15 minutes and it is 29 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2011. 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 5 hours and 31 minutes longer than the mean synodic month length. It is 1 hour and 32 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠139.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠139.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠167°.

Moon before perigee

11 days since point of apogee on 6 February 2011 at 23:13 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next day until the Moon reaches the point of next perigee on 19 February 2011 at 07:27 in ♍ Virgo.

Distance to Moon 365 068 km

The Moon is 365 068 km (226 843 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 358 247 km (222 604 mi).

Moon after descending node

4 days after descending node on 14 February 2011 at 08:14 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 26 February 2011 at 20:19 in ♐ Sagittarius.

Moon after northern standstill

5 days since the last northern standstill on 13 February 2011 at 09:00 in ♊ Gemini when the Moon has reached North declination of ∠24.080° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-23.985° at the point of next southern standstill on 25 February 2011 at 22:13 in ♐ Sagittarius.

Draconic month

18 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.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
