Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 30 January 2010 at 06:18.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♌ Leo

Moon is leaving the last ∠1° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.

Apparent angular diameter ∠1970"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1947".

Wolf Moon before 1 day

Next Full Moon is the Snow Moon of February 2010 after 28 days on 28 February 2010 at 16:38.

Upcoming main Moon phases

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.

Lunation 124 / 1077

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 124 of Meeus index or 1077 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.82 days

The length of the lunation is 29 days, 19 hours and 40 minutes. This is the year's longest synodic month of 2010. It is 1 hour and 30 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 6 hours and 56 minutes longer than the mean synodic month length. It is 7 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠164.3°

At the beginning of the lunation cycle the true anomaly is ∠164.3°. At the beginning of next synodic month the true anomaly is going to be ∠188.9°.

Moon after perigee

1 day after point of perigee on 30 January 2010 at 09:03 in ♌ Leo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next apogee on 13 February 2010 at 02:06 in ♒ Aquarius.

Previous perigeeNext apogee

Distance to Moon 363 935 km

The Moon is 363 935 km (226 139 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 406 542 km (252 613 mi).

Moon after descending node

2 days after descending node on 29 January 2010 at 00:02 in ♋ Cancer. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 11 February 2010 at 04:58 in ♑ Capricorn.

Draconic month

16 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the second to the final part of the cycle.

Moon after northern standstill

4 days since the previous standstill on 26 January 2010 at 21:04 in ♊ Gemini when the Moon has reached North declination of ∠25.783°, the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-25.749° at the point of next southern standstill on 8 February 2010 at 14:27 in ♐ Sagittarius.

Syzygy in 13 days

In 13 days on 14 February 2010 at 02:51 in ♒ Aquarius the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
