Moon – Jupiter Conjunction

   Wednesday morning January 30th, at sunrise, the 25-day old waning crescent Moon will be within 2-3o from the planet Jupiter. Venus is a few more degrees further east and the Moon will be in conjunction with Venus on the 31st.

Moon Passes Spica

   Shortly after midnight local time on January 26th-27th the 20-21 day old waning gibbous Moon will pass within 10-11o from the blue-white star Spica. This star marks a bundle of wheat in the left hand of Virgo the Harvest Maiden.

Moon – Regulus Conjunction

   Tuesday evening January 22rd the 17-day old waning gibbous Moon will be about 2o from the heart of the ‘Lion’, the star Regulus in the constellation Leo the Lion. Regulus marks the bottom of the backward question mark shape of the head and chest of the Lion.

    Both the Moon and Regulus will easily fit within the field of view of binoculars.

January Moon at Perigee

click on graphic to see it larger   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Monday January 21st. At that time the Moon will be at a distance of 28.015 Earth diameters 357,345 km (222,044 miles) from the Earth.

   The 16-day old Waning gibbous Moon rises shortly after sunset local time is visible all night. Over the southwestern horizon, as the Moon is rising,is the planet Mars which sets around midnight.

   Does our Moon actually go around the Earth as this graphic shows? 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*

January Full Moon at Ascending Node, Almost at Perigee, and a Total Lunar Eclipse

   Sunday January 20th the full 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.

Total Lunar Eclipse   On the day of the node crossing the full Moon also be passing through the Earth’s shadow giving us a Total Lunar Eclipse that will be visible across the continental U.S.A.

   Within less than 15 hours the Moon will also be at perigee, is closest to the Earth for this orbit. This full Moon will be the second closest perigee Moon this year, with the perigee Moon of February as the closest and the ‘Super Moon’ for the year.

   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*

Moon and the Hyades

   Wednesday and Thursday January 16th and the 17th the waning gibbous Moon will be passing past the open star cluster the Hyades and the reddish star Aldebaran. This is a v-shaped group of stars that make up the face of Taurus the Bull. The Hyades is one of two open star clusters in the constellation Taurus. The other is a small dipper-shaped group of stars, the Pleiades, located on the shoulder of Taurus.

Moon – Uranus Conjunction

   Monday evening January 14th the 9-day old waxing gibbous Moon will be about 6-7o from the outer planet Uranus. Both are close enough to fit within a binocular field of view.
   However don’t realistically expect to see Uranus as Uranus has an apparent magnitude of 5.78 compared to the much brighter -12.0 apparent magnitude of the Moon.
