First Quarter in Taurus

First Quarter on . The illuminated surface of the moon is 62% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 2 February 2066 at 05:44 UTC.

Moonrise and moonset

The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon phase and lunation details

Moon in ♉ Taurus

Moon is leaving the last ∠1° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Snow Moon after 6 days

Next Full Moon is the Snow Moon of February 2066 after 6 days on 10 February 2066 at 08:29.

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 ∠1771"

Lunar disc appears visually 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1946".

Lunation 817 / 1770

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 817 of Meeus index or 1770 from Brown series.

Synodic month length 29.53 days

The length of this lunation is 29 days, 12 hours and 36 minutes and it is 47 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 shorter than mean

The length of the current synodic month is 8 minutes shorter than the mean synodic month length. It is 6 hours and 1 minute longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠35.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠35.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠61.6°.

Moon before apogee

10 days since point of perigee on 23 January 2066 at 15:57 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 4 February 2066 at 09:58 in ♊ Gemini.

Distance to Moon 404 815 km

The Moon is 404 815 km (251 540 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 789 km (251 524 mi).

Moon before descending node

9 days after ascending node on 24 January 2066 at 14:22 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 7 February 2066 at 15:03 in ♋ Cancer.

Moon before northern standstill

11 days since the last southern standstill on 22 January 2066 at 16:31 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.483° the lunar orbit is extending northward over the next day to face maximum declination of ∠25.448° at the point of next northern standstill on 5 February 2066 at 06:59 in ♊ Gemini.

Draconic month

9 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 10 February 2066 at 08:29 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.
