the Moon and the Beehive Cluster

   During the early morning hours of November 7th and 8th our Moon, as it wanes from gibbous to last quarter, will be passing by M-44, an open star cluster. M-44 is also known as the Beehive Cluster, and is located within the constellation Cancer the Crab.

Moon Faces Off With Taurus

   Monday evening November 2nd the 17-day old waning gibbous Moon will be alongside the open star cluster the Hyades, a v-shaped group of stars making up the face of Taurus the Bull. The ‘angry eye’ of the Bull, the reddish star Aldebaran, is about 2-3o from the Moon.

   Look for Mars off to the west from the Moon, and Jupiter and Saturn further west over the southwestern horizon.

Moon May Get Stung!

   Sunday morning October 11th the 23.6-day old waning crescent Moon will be about 2o from the open star cluster M-44, also known as the Beehive Cluster. This is a group of a few hundred stars located within the constellation Cancer the Crab.

   Despite the large difference in apparent magnitude (Moon: -11.4 : Beehive Cluster: 3.4) The Beehive Cluster could still be visible with an optical aid or camera.

Last Night Had It’s Hang-ups!

   Last evening was another opportunity to image the ISS as it passed over my part of the world. So I did!
   While out in the backyard I aimed my camera nearly straight up to get a picture of one of my favorite parts of the sky. This is near the star Altair in the constellation Aquila the Eagle. Near Altair is the ‘tiny’ constellation of Delphinus the Dolphin. Looking further upward from the kite or diamond-shape stars there is another smaller constellation, Sagitta the Arrow.
   If you find Sagitta use the two stars at the end as ‘pointer stars’ and they will direct your eyes to a neat little star cluster, Brocchi’s Custer, also known as the Coathanger Cluster.

Moon-Venus Conjunction + M44

   Monday morning September 14th look eastward in the pre-dawn skies for the 26-day old waning crescent Moon to be about 4-5o from the planet Venus and about the same distance from the open star cluster M-44, the Beehive Custer.

   The trio should make for an interesting view with binoculars.

Moon – Aldebaran Conjunction

   Thursday morning August 13th the 24-day old waning crescent Moon will be about 2-3o from the reddish star Aldebaran in Taurus the Bull. Aldebaran is one of the stars making the eyes of the Bull and both of these stars are at the open ends of a v-shaped group of stars. an open star cluster knowns as the Hyades.
   The combination of the stars of the Hyades with the thin waning crescent Moon should make a striking sight through binoculars.

Venus Pass by M-35

Tuesday morning August 11th the inner planet Venus will be about 3-4o from the open star cluster M-35. Located near the feet of the Gemini Twins M-35 contains thousands of stars within an area about the size of the full Moon. M-35 is located around 5,000 light years distant.

   M-35 has an apparent magnitude of approximately 5.0 so it is possible to see M-35 with the naked eye and is certainly easily seen with binoculars. For the ‘record’ Venus has an apparent magnitude of -4.31, which by comparison is ‘way brighter’!!

Jupiter at Opposition

Zooming in on Jupiter at Opposition   Tuesday July 14th the outer giant ringed planet Jupiter reaches the point in its orbit around the Sun that places the Earth in between Jupiter and the Sun. This is known as opposition, and opposition is an orbital position that applies to solar system objects (outer planets, dwarf planets, asteroids, comets, etc.) orbiting the Sun beyond the Earth’s orbit. An object at opposition will have approximately the same heliocentric longitude as the Earth’s heliocentric longitude. So on Tuesday both planets will have a heliocentric longitude of around 228o.
   An opposition of Jupiter occurs approximately every 13 months because both Earth and Jupiter are moving. After one Earth Revolution, an Earth year, the planet Earth will be where it was the previous year at opposition with Jupiter. However Jupiter will not be there because it has moved during the past year as well. It will take the Earth about an extra month or so to catch up with Jupiter. Earth moves 360o each year while Jupiter moves approximately 12o each Earth year.
Sunset Local Time Sunset Local Time.
   When an object is at opposition it rises at approximately the same time as local sunset and that same object at opposition sets at approximately the time of local sunrise. In other words an object at opposition will be up all night from sunrise to sunset.
   Picture our Moon at full phase and how it is directly opposite the Sun, with the Earth in between. The full Moon in effect is at opposition but we call it the full Moon instead. And so both the full Moon and Jupiter at opposition, rise at sunset, set at sunrise, and both will be visible all night.

   Jupiter is currently a few degrees to the west from Saturn and both rise and set together, although Saturn will not reach its opposition for a few more days, on the 20th of this month.

Comet NEOWISE or NEOWOW!!

   Could it get much better than this? Five visible planets (Jupiter, Saturn, Mars, Venus, Earth); Moon-Mars conjunction; Venus-Aldebaran conjunction; 2 outer planets and a Dwarf Planet not naked-eye visible, and Comet 2020 F3 (NEOWISE). Icing on the ‘cake’ would have been to have the ISS orbit through the sky this morning.

Taurus Eyes Venus

   Saturday morning July 11th the inner planet Venus will be about 1o from the reddish star Aldebaran in Taurus the Bull. Aldebaran marks the ‘angry eye’ of the bull and is at one end of a v-shaped group of stars, the Hyades, that make up the face of Taurus.

   Venus has just spent the past several days traversing the Hyades, an open star cluster composed of hundreds of stars. The Hyades, at a estimated distance of 150 light years, is the closest open star cluster in our galaxy to the Earth.
    With binoculars the view of Venus, the Hyades, and Aldebaran is striking with Venus brightly shining at about a -4.5 apparent magnitude and Aldebaran with a 0.9 apparent magnitude.

   Also on this day the 20-day old waning gibbous Moon will be about 4-5o from the planet Mars.
