Waning Crescent Moon Near Beehive Cluster

   Wednesday morning, August 28th, before the Sun rises local time look for the very thin 27-day old waning crescent Moon to be ‘on top’ of the open star cluster the Beehive Cluster, M-44. This should prove to be a great sight either with binoculars or telescope.

August Moon at Ascending Node – Let the Twins Show you Where

   Tuesday August 27th the 26-day old thin waning crescent 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 waning gibbous Moon will be about 2-3o from Pollux, one of the 2 ‘Twin’ stars of Gemini.

   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*

July Moon at 2nd Ascending Node

   Tuesday July 30th the 27.5-day old thin waning crescent 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 very thin waning crescent Moon rises about an hour before the Sun rises and is located nearly directly west from the ‘Twin’ stars, Pollux and Castor.

A Bullish Moon, or A Moon – Bull Conjunction, or Bull Gets Mooned!

   Over the next 3 mornings, July 26, 27,and 28 before sunrise, the waning crescent Moon will be moving across the shoulders and head of the constellation Taurus the Bull. As it traverses the constellation pattern the waning Moon will come within about 8o from the open star cluster, the Pleiades and within about 4-5o from the v-shaped open star cluster the Hyades.
   This should make for some good viewing through binoculars, especially on the 27th when the Moon passes about 2-3o from the reddish star Aldebaran in the Hyades. How close the conjunction between the Moon and Aldebaran will be depends greatly on your viewing location’s longitude. This graphic is for when the two are their closest which is 2.5o around 1 UT (8 pm CDT).

Waning Crescent Moon and Open Star Clusters

   Sunday morning June 30th, before sunrise local time, look for a thin 27-day old waning crescent Moon to be close to the two open star clusters in Taurus the Bull, the Pleiades and the Hyades. The Pleiades are about 9-10o west, or above, the Moon, while the v-shaped Hyades and the Moon will all fit within the field of view of binoculars.

Waning Crescent Moon Passes Uranus

   Thursday and Friday mornings before the Sun rises look toward the eastern horizon for the 24-day old waning crescent Moon to be within about 8-9o to the west from the outer ringed planet Uranus on Thursday the 27th, and about 7-8o from Uranus but now to the east on Friday the 28th.


   Uranus has an apparent magnitude 5.84 which technically makes it naked-eye visible (in dark skies) however nearby is the thin waning crescent Moon outshining Uranus with a -11.00 apparent magnitude. Worth mentioning but not naked eye visible is the outermost of the 8 planets, Neptune, with a 7.90 apparent magnitude.

Waning Crescent Moon – Venus Conjunction

   Saturday morning June 1st watch for a very thin 27.5-day old waning crescent Moon to rise with the inner plane Venus. The Moon will be about 5o from Venus, and despite the Moon’s thin appearance its apparent magnitude of -9.0 will still outshine Venus apparent magnitude of -3.80. Nonetheless both should make a striking pair over the horizon before sunrise local time.
