First Quarter in Pisces

First Quarter on . Illuminated surface of the Moon is 55% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 22 November 2001 at 23:21 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 ♓ Pisces

Moon is passing about ∠7° of ♓ Pisces tropical zodiac sector.

Beaver Moon after 7 days

Next Full Moon is the Beaver Moon of November 2001 after 7 days on 30 November 2001 at 20:49.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1768"

Lunar disc appears visually 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1943".

Lunation 23 / 976

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 23 of Meeus index or 976 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 7 minutes and it is 2 hours and 34 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 1 hour and 23 minutes longer than the mean synodic month length. It is 5 hours and 40 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠53.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠53.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠86.2°.

Moon at apogee

Moon is at apogee at 15:46 about 11 days since last perigee on 11 November 2001 at 17:37 in ♍ Virgo the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 13 days until point of next perigee on 6 December 2001 at 22:48 in ♌ Leo.

Distance to Moon 404 396 km

This apogee Moon is 404 396 km (251 280 mi) away from Earth. It is 1 012 km further than the mean apogee distance, but it is still 2 313 km closer than the farthest apogee of 21st century.

Moon after descending node

5 days after descending node on 17 November 2001 at 19:51 in ♐ Sagittarius 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 2 December 2001 at 05:30 in ♊ Gemini.

Moon after southern standstill

4 days since the last southern standstill on 18 November 2001 at 22:30 in ♑ Capricorn when the Moon has reached South declination of ∠-24.211° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠24.246° at the point of next northern standstill on 3 December 2001 at 06:54 in ♋ Cancer.

Draconic month

18 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 30 November 2001 at 20:49 in ♊ Gemini 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.
