The Moon this morning, September 12th at 5:50 am CDT within about 0.5o from the star Aldebaran in Taurus the Bull. None of the other stars making up the v-shaped open star cluster the Hyades were visible as the reflected light from the Moon was too bright.

Tuesday September 12th the 18-day old waning gibbous Moon will be once again poking Taurus the Bull in the eye! Actually the Moon will be within about 0.5o from the reddish star Aldebaran, the ‘angry eye’ of Taurus.
some extra Bob’s Space
With binoculars the view of the Moon this close to Aldebaran and the rest of the v-shaped group of stars making up the open star cluster the Hyades should be as good as this graphic shows. But minus the blue lines!
Thursday morning July 20th watch for the thin 26-day old waning crescent Moon to be within 2-3o from the inner planet Venus as both rise a couple of hours before sunrise. The reddish star Aldebaran in Taurus the Bull will be about 10o from the Moon.
Venus and the Moon will fit nicely within the field of view of binoculars.
Monday morning July 17th the 23-day old waning crescent Moon will be within a few degrees from the outer planet Uranus and dwarf planet Eris.
Another dwarf planet, Ceres, the closest dwarf planet to the Earth is above the north-eastern horizon before sunrise local time. Ceres, formerly known as an asteroid, and the largest of the main belt asteroids, had enough mass to form into a spherical shape, one of the requirements for planet classification. Thus allowing it to be included in the group of known dwarf planets – most of which reside in orbits beyond the outer planet Neptune.
Also very visible over the eastern horizon is the inner planet Venus shining very brightly near the reddish star Aldebaran in Taurus the Bull.
Thursday July 13th morning in the couple of hours before sunrise local time the inner planet Venus will be within about 3o from the reddish star Aldebaran in Taurus the Bull. Aldebaran is often described as the “red, angry eye” of Taurus. It is located at the end of the v-shaped open star cluster the Hyades, a ‘loose’ grouping of several hundred stars of which the brightest form the v-shape of the Bull’s face.
On the 13th Venus becomes the other eye of the Bull. The apparent brightness or magnitude difference between Venus (-4.07) and Aldebaran (0.84) is quite striking.
Over the next few days Venus will steadily move away, toward the east, from Aldebaran as this animated graphic is showing. It is a simulated view through 10×50 binoculars and runs from July 12th to July 17th.
Friday evening March 31st the 4-day old waxing crescent Moon will be about 4o from the reddish star Aldebaran in the open star cluster The Hyades. This open star cluster has a noticeable v-shape and from mythology the v-shape is the face of Taurus the Bull. Over the course of several hours as the Moon continues moving eastward along its orbit the Moon will pass across the v-shape and will be less than one-half degree from Aldebaran.
From my longitude this part of the sky will have set but observers in parts of north Africa, India, and that part of the world may be able to see an occultation of Aldebaran by the Moon. This animated graphic shows the Moon’s motion from 9 pm CDT 31 March to 5 am CDT 1 April (2 UT 1 April to 9 UT 1 April).
The point of the v-shape is the bull’s nose while the two stars at the open end, Aldebaran and Epsilon Taurus mark the bull’s eyes. To the right, west, from the Moon is another open star cluster The Pleiades.
The Moon reaches perigee, (minimum distance from Earth), this month on Monday December 12th. At that time the Moon will more or less be at a distance of 28.1 Earth diameters (356,509 km or 221,524 miles) from the Earth.
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*
On the day of the lunar perigee the 13.5-day old waxing gibbous Moon rises at around sunset local time and is over the southwest horizon at sunrise the following morning. The Moon is also very close to the star Aldebaran in the v-shaped open star cluster making the face of Taurus the Bull, the Hyades. Depending on your location this may be an occultation of the star by the Moon, or a very close conjunction. Nonetheless with binoculars or a wide field telescope eyepiece the Moon superimposed on the Hyades should make for great viewing.
