First Quarter in Taurus

First Quarter on . Illuminated surface of the Moon is 51% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 12 February 2038 at 09:30 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 in ♉ Taurus

Moon is passing about ∠25° of ♉ Taurus tropical zodiac sector.

Snow Moon after 7 days

Next Full Moon is the Snow Moon of February 2038 after 7 days on 19 February 2038 at 16:09.

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 ∠1792"

Lunar disc appears visually 8.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1792" and ∠1943".

Lunation 471 / 1424

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 471 of Meeus index or 1424 from Brown series.

Synodic month length 29.72 days

The length of this lunation is 29 days, 17 hours and 23 minutes and it is 5 minutes shorter than the upcoming lunation's length. 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 4 hours and 39 minutes longer than the mean synodic month length. It is 2 hours and 24 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠117.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠117.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠149.9°.

Moon after apogee

3 days since point of apogee on 9 February 2038 at 10:00 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 21 February 2038 at 08:05 in ♍ Virgo.

Distance to Moon 399 990 km

The Moon is 399 990 km (248 542 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 360 960 km (224 290 mi).

Moon before ascending node

10 days after descending node on 2 February 2038 at 05:08 in ♑ Capricorn 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 16 February 2038 at 17:30 in ♋ Cancer.

Moon before northern standstill

10 days since the last southern standstill on 1 February 2038 at 15:22 in ♑ Capricorn when the Moon has reached South declination of ∠-22.196° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠22.250° at the point of next northern standstill on 16 February 2038 at 04:53 in ♋ Cancer.

Draconic month

23 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 19 February 2038 at 16:09 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.
