Moon – Aldebaran Conjunction

   Tuesday evening March 12th the 6-day old waxing crescent Moon will be about 4o from the reddish star Aldebaran in the constellation Taurus the Bull. Aldebaran is also the brightest in the open star cluster the Hyades, a v-shaped appearing group of stars making the face of Taurus. Both the Moon and the v-shape of the Hyades should fit nicely within the field of view of 7×50 binoculars.

    Aldebaran, from mythology, represents the ‘angry eye’ of the bull as it charges toward Orion.

Moon – Mars Conjunction

   Monday evening March 11th the 5-day old waxing crescent Moon will be about 7o from the outer terrestrial planet Mars. Both the Moon and Mars will be over the western horizon at sunset, and both should fit nicely within the field of view of 7×50 binoculars.

Moon Conjunction with Uranus

   Saturday evening March 9th the thin 3-day old waxing crescent Moon will be about 6-7o from the outer planet Uranus. Both will be above the western horizon at sunset local time, setting about 2 hours after the Sun sets.
   Is it possible to see Uranus? Currently the apparent magnitude of Uranus is within the range that is visible to the unaided eye in very dark skies, or at least with binoculars. However even at a thin crescent shape the nearby Moon may brighten the sky too much to allow for seeing Uranus. There is a noticeable difference in the apparent brightness of the crescent Moon and Uranus. The Moon has a -10.0 apparent magnitude compared to Uranus with a 5.87 apparent magnitude.
   Despite the moonlight Uranus is visible as a faint star through binoculars at its current apparent magnitude and using the Moon as a guide it may be possible to spot Uranus. You may just have to wait until the Moon rises well after sunset leaving the sky relatively darker.

March Moon at Descending Node

   Saturday March 2nd 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 26-day old waning crescent Moon will be over the southeast horizon rising about 1-2 hours before the Sun rises. Toward the west from the Moon will be two outer planets, Saturn and Jupiter, and a bit further west the dwarf planet Ceres. About 4-5o east from the Moon is the inner planet Venus. Both will easily 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 Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Wednesday January 9th. At that time the Moon will more or less be at a distance of 31.83 Earth diameters 406,116 km (252,349 mi.) 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 4-day old waxing crescent Moon will be over the southwestern horizon at sunset local time.
