Waxing Crescent on . The illuminated surface of the moon is 17% and growing larger. The lunar cycle is 4 days young.
The moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Main moon phases of the following lunar cycle.
Moon is passing about ∠7° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the New Moon before 4 days on 3 February 2011 at 02:31.
Next Full Moon is the Snow Moon of February 2011 after 10 days on 18 February 2011 at 08:36.
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 9.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1945".
The Moon is 4 days young and navigating from the beginning to the first part of the current synodic month. This is lunation 137 of Meeus index or 1090 from Brown series.
The length of this lunation is 29 days, 18 hours and 15 minutes and it is 29 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2011. 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°).
The length of the current synodic month is 5 hours and 31 minutes longer than the mean synodic month length. It is 1 hour and 32 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 ∠139.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠167°.
1 day since point of apogee on 6 February 2011 at 23:13 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 19 February 2011 at 07:27 in ♍ Virgo.
The Moon is 405 102 km (251 719 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 358 247 km (222 604 mi).
7 days after ascending node on 30 January 2011 at 18:29 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 14 February 2011 at 08:14 in ♋ Cancer.
8 days since the last southern standstill on 29 January 2011 at 16:26 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.180° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠24.080° at the point of next northern standstill on 13 February 2011 at 09:00 in ♊ Gemini.
7 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.
In 10 days on 18 February 2011 at 08:36 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.
