First Quarter on . The illuminated surface of the moon is 61% and growing larger. The lunar cycle is 8 days young.
* The exact date and time of this First Quarter phase is on 3 September 2003 at 12:34 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 about ∠24° of ♐ Sagittarius tropical zodiac sector.
Next Full Moon is the Harvest Moon of September 2003 after 6 days on 10 September 2003 at 16:36.
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.
Lunar disc appears visually 2.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1958" and ∠1903".
The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 45 of Meeus index or 998 from Brown series.
The length of this lunation is 29 days, 9 hours and 43 minutes and it is 2 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 3 hours and 1 minute shorter than the mean synodic month length. It is 3 hours and 8 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠301° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠325.5°.
3 days since point of perigee on 31 August 2003 at 18:47 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 16 September 2003 at 09:22 in ♉ Taurus.
The Moon is 366 176 km (227 531 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 404 713 km (251 477 mi).
2 days after descending node on 2 September 2003 at 07:23 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 September 2003 at 23:28 in ♉ Taurus.
12 days since the last northern standstill on 23 August 2003 at 11:41 in ♋ Cancer when the Moon has reached North declination of ∠26.649° the lunar orbit is extending southward over the next day to face maximum declination of ∠-26.746° at the point of next southern standstill on 5 September 2003 at 11:54 in ♑ Capricorn.
15 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.
In 6 days on 10 September 2003 at 16:36 in ♓ Pisces 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.
