When the Moon Hits Your Eye

Thursday evening October 17th look for the 19-day old waning gibbous Moon to be rising with the stars of the open star cluster the Hyades. The Moon will be about 3-4o from the reddish star Aldebaran. Aldebaran represents the ‘angry eye’ of Taurus the Bull, and is at the end of the v-shaped asterism, the Hyades.

Waning Gibbous Moon Near the Hyades

   Late Thursday night September 19th or very early Thursday morning September 20th the 22-day old waning gibbous Moon will be rising with the stars making up the v-shaped face of Taurus the Bull. These are the Hyades. The point of the v-shape is the nose of the bull while at the opposite ends are the eyes. Most noticeably is the reddish star Aldebaran, which from the mythology is the Bull’s ‘angry eye’.

   The Moon will be about 4-5o to the west from Aldebaran and will may occult some of the stars making up the Hyades. At sunrise local time the Moon will be over the southern horizon and then sets around midday or early afternoon.

September Apogee Moon

   Our Moon reaches apogee, (greatest distance from Earth), for this orbit, on Friday August 13th. At that time the Moon will be at a distance of 31.85 Earth diameters 252,511 miles (406,378 km) from the Earth.

   On the day of the apogee Moon the 14-day old full Moon rises around sunset local time and is above the horizon the remainder of the night hours, setting at around sunrise the following morning.

   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*

Neptune at 2019 Opposition

   Tuesday September 10th the outer planet Neptune reaches a position in its orbit around the Sun when it is on the opposite side of the Earth from the Sun. This coincidentally is known as opposition, and it is an orbital position which only the planets further from the Sun than the Earth may reach.
   At opposition an object orbiting the Sun beyond Earth’s orbit rises and sets in a fashion similar to our Moon when it is at full phase, in that the object at opposition rises at sunset and sets at sunrise.
   Neptune is over the eastern horizon after sunset local time and with an apparent magnitude of 7.81 is beyond unaided-eye visibility but could be visible with large aperture telescopes or with a camera.

   Saturday morning August 24th about an hour before sunrise local time look for the 23-day old waning gibbous Moon to be about 1o from the reddish star Aldebaran. Aldebaran represents the ‘angry eye’ of Taurus the Bull, and is at the end of the v-shaped open star cluster, the Hyades.

August Apogee Moon

   Our Moon reaches apogee, (greatest distance from Earth), for this orbit, on Saturday August 17th. At that time the Moon will be at a distance of 31.84 Earth diameters 251,954 miles (405,480 km) from the Earth.

   On the day of the apogee Moon the 17-day old waning gibbous Moon rises about 1 hour before midnight local time and sets later the following morning.
