February Moon At Ascending Node

   Sunday February 17th the 13-day old waxing gibbous Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   On the day of the node crossing the 13-day old waxing gibbous Moon rises about an hour after sunset local time.

   Does our Moon actually go around the Earth as many graphics show? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

Taurus Gets ‘Moon Eye’

   Wednesday evening, February 13th the 9-day old waxing gibbous Moon will be within about 1o from the reddish star Aldebaran in the open star cluster the Pleiades. The v-shaped Pleiades make up the face of Taurus the Bull and the star is often referred to as the angry eye of the bull due to the star’s reddish color. The entire star cluster and the Moon all fit well within the field of view of binoculars.

    Further west is a planetary conjunction between Mars and Uranus. Both will fit well within the field of view of binoculars.

Moon – Mars Conjunction


   Sunday evening, February 10th, after sunset local time the 6-day old waxing crescent Moon will be 6-7o from the planet Mars. Close enough to fit within the field of view of 7×50 binoculars.

February Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Tuesday February 5th. At that time the Moon will more or less be at a distance of 31.87 Earth diameters 406,556 km (252,622 miles) from the Earth.

   Does our Moon actually go around the Earth? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

   On the day of the apogee the 1.5-day old very thin waxing crescent Moon will be over the southwestern horizon at sunset local time.

January Moon at Descending Node


   Sunday February 3rd the Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.
   On the day of the node crossing the Moon will be over the southeast horizon rising about an 30 minutes before the Sun rises. New Moon is the next day, February 4th, and is too close to the Sun to be seen.
   While the Moon may not be visible there are several planets and bright stars visible in the hour or so before the Sun rises.

Moon – Saturn Conjunction

   Saturday morning February 2nd the thin 27.5-day old thin waning crescent Moon will be 1-2o from the ringed planet Saturn. Both will be rising about 1 hour before the Sun rises, and the two will easily fit within the field of view of binoculars.
