2019-Sun Enters Ophiuchus

ophiuchus   Saturday, November 30th the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Scorpius the Scorpion and into the constellation of Ophiuchus the Healer. This is the true or actual position of the Sun as opposed to the pseudoscience of astrology which usually has the astrological Sun one constellation ahead or east from the Astronomical Sun’s position.

ophiuchus-scorpion   Ophiuchus is the 13th constellation of the zodiac (Astronomical) but does not appear in the astrological zodiac nor in the astrology column found in many newspapers. A constellation of either zodiac is defined the same way, using the ecliptic path. If the ecliptic passes through a constellation boundary then that constellation is a zodiac constellation. In the graphics I use the ecliptic path clearly crosses across the boundary for the constellation Ophiuchus the Healer.

   Ophiuchus is described in a mythology story as a healer. In one story following a mortal fight between Orion and Scorpius the Scorpion Ophiuchus kills the scorpion by stepping on it; extracts the venom from the scorpion; and then uses it to bring Orion back to life.
cadeuces   In Ophiuchus’s hands he is holding a long snake, the 2-part constellation of Serpens – Serpens Cauda (tail of the snake) and Serpens Caput (head of the snake). There are many stories about Ophiuchus and the snake including one where this is the origin of the symbol for medicine, the caduceus. However the caduceus is used primarily in the United States as the symbol for medicine, and is depicted as 2 snakes wrapped around a staff with wings. rodIf there is a connection with a medical symbol then it should be with the Rod of Asclepius, a staff with one snake.

Sun Does Not Enter Sagittarius

  According to the pseudoscience of astrology the Sun enters the constellation of Sagittarius the Archer on Friday November 22nd. When in fact the actual position of the Sun is still within the boundaries of the constellation of Libra the Scales. And 2-3 days later the Sun will have entered the Astronomical constellation of Scorpius the Scorpion.

   Read a little more about how astrology has the Sun incorrectly placed in a previous blog, and in another blog discussing the effects of precession.

Mercury at Inferior Conjunction – Transits the Sun

   Are you ready for the Solar Transit Monday morning November 11th? This celestial event will be visible across the entire continental U.S.A., and your longitude/location will determine when and how much of the transit you will be able to see. Weather cooperating of course!

Visualize the Ecliptic

Above the Terrestrial Planets this Month

   Once in a while the planets are arranged such that they are spread across the sky. The planets are not lined up in a straight line outward from the Sun but rather are arranged along the ecliptic. The ecliptic is the Earth’s orbital path around the Sun and the respective orbit of each planet is inclined from the ecliptic. And this is one of those times when it is easier to visualize the ecliptic. (see graphics below) Click here to read a previous posting about the ecliptic and planet inclination.

   As the animated graphic is showing the terrestrial planets are not arranged in a straight line. This graphic shows the solar system out to Neptune and from this perspective the planets are obviously not in a straight line.

Sun Does Enter Libra – 2019

310ct-view-from-earth   Thursday October 31st the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Virgo the Harvest Maiden and into the constellation of Libra the Scales. This is the true or actual position of the Sun as opposed to the pseudoscience of astrology which usually has the astrological Sun one constellation ahead or east from the Astronomical Sun’s position.

Uranus at Opposition – 2019

view-from-uranus
   Monday October 28th the outer planet Uranus 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 the outer planet rises and sets in a fashion similar to our Moon when it is at full phase, in that the outer planet at opposition rises at sunset and sets at sunrise.

   On the date of the opposition Uranus will be over the eastern horizon after sunset and currently with an apparent magnitude of between 5 an 6 Uranus may be visible with binoculars and certainly with a telescope.

Along the Ecliptic

   Every once in a while the planets arrange themselves along the horizon and when that happens visualizing the ecliptic is somewhat obvious. For the next week or so all of the naked-eye visible planets except Mars, plus Neptune and Dwarf Planet Ceres, will be above the horizon at sunset local time. If you wait about an hour the Moon and the planet Uranus will rise above the eastern horizon as Mercury and Venus have set in the west.
   The ecliptic is actually the Earth’s orbit and it is used as a reference ‘line’, properly known as the plane of the ecliptic, for all of the Sun orbiting objects. Since few if any Sun orbiting objects have orbits that are on the same plane as the Earth but rather these objects are tilted or inclined either above or below the plane of the ecliptic. This is know as inclination. (Table Source: https://en.wikipedia.org/wiki/Orbital_inclination)
