First Quarter on . The illuminated surface of the moon is 63% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 4 March 2009 at 07:46 UTC.
The moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Main moon phases of the following lunar cycle.
Moon is passing first ∠0° of ♋ Cancer tropical zodiac sector.
Next Full Moon is the Worm Moon of March 2009 after 5 days on 11 March 2009 at 02:38.
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.
Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1934".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 113 of Meeus index or 1066 from Brown series.
The length of this lunation is 29 days, 14 hours and 31 minutes and it is 3 hours and 14 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 1 hour and 47 minutes longer than the mean synodic month length. It is 5 hours and 16 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠246.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠282.4°.
13 days since point of apogee on 19 February 2009 at 17:00 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 7 March 2009 at 15:06 in ♋ Cancer.
The Moon is 363 406 km (225 810 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 367 020 km (228 056 mi).
10 days after ascending node on 22 February 2009 at 20:31 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from North to South in descending node on 8 March 2009 at 04:05 in ♌ Leo.
1 day since the last northern standstill on 4 March 2009 at 21:34 in ♊ Gemini when the Moon has reached North declination of ∠26.987° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-26.896° at the point of next southern standstill on 18 March 2009 at 05:07 in ♐ Sagittarius.
10 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the beginning to the first part of the lunar cycle.
In 5 days on 11 March 2009 at 02:38 in ♍ Virgo 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.
