Waxing Gibbous in Cancer

Waxing Gibbous on . Illuminated surface of the Moon is 89% and growing larger. Lunar cycle is 11 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 ♋ Cancer

Moon is passing about ∠17° of ♋ Cancer tropical zodiac sector.

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 11 February 2011 at 07:18.

Snow Moon after 2 days

Next Full Moon is the Snow Moon of February 2011 after 2 days on 18 February 2011 at 08:36.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1909"

Lunar disc appears visually 1.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1909" and ∠1942".

Lunation 137 / 1090

The Moon is 11 days young and navigating from the first to 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

8 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 3 days until the Moon reaches the point of next perigee on 19 February 2011 at 07:27 in ♍ Virgo.

Distance to Moon 375 516 km

The Moon is 375 516 km (233 335 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 358 247 km (222 604 mi).

Moon after descending node

1 day after descending node on 14 February 2011 at 08:14 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 11 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

2 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 10 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

15 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 2 days

In 2 days on 18 February 2011 at 08:36 in ♌ Leo 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.
