Moon in a Face-Off with Taurus


   Sunday September 30th the 20-day old waning gibbous Moon will be within 1-2o from the reddish star Aldebaran in the open star cluster the Hyades. The Hyades are a v-shaped group of stars making up the face of Taurus the Bull.
Aldebaran is at the tip of one of the
lines making up the v-shape and, with its reddish color, represents the ‘angry eye’ of the Bull.

Moon Traverses Taurus


   Wednesday and Thursday evenings March 21st and 22nd the waxing crescent Moon will pass across the constellation of Taurus the Bull. It will first be several degrees from the open star cluster the Pleiades and then the next day the Moon will be within 1-2o from the reddish star Aldebaran and the open star cluster the Hyades. The latter should prove to be a striking sight through binoculars.

Taurus Eyes the Moon

   Saturday evening December 30th the 13-day old waxing gibbous Moon will be 1-2o from the reddish star Aldebaran. The star is often described as representing the angry eye of Taurus the Bull. Regardless Aldebaran is at one end of a v-shaped group of stars that make-up the face of Taurus. These stars are part of an open star cluster, the Hyades, consisting of several hundreds of stars located about 150 light years from the Earth.

   About 10o from the Hyades, on the shoulder of Taurus, is another well-known open star cluster – the Pleiades. This is a cluster of approximately 1,000 stars located at a distance of 400-450 light years. Easily seen with the naked-eye several of the brightest stars form a small dipper-shape.

2017 June Solstice

21june-ecliptic   Northern hemisphere spring comes to an end and its summer begins on Wednesday day June 21st at 4:24 UT (11:24 pm CDT Tuesday June 20th) when the Sun ‘reaches’ the celestial coordinates of 23.5o north declination and 6 hours right ascension. With respect to the Earth’s surface the Sun is described as over the Tropic of Cancer, 23.5o, north latitude of the Earth’s equator. At this same time the Sun is just entering the boundaries of the astrological constellation Cancer the Crab. Interestingly about 11 hours later, June 21st at 15 UT (10 am CDT) the Sun will actually be entering the region of the Gemini Twins as it crosses the boundary between Gemini and Taurus.
Just had to include this!!
   According to the pseudoscience of astrology the Sun, at this date, would be entering the astrological sign of Cancer the Crab.

   We know that it is the Earth’s orbital motion around the Sun that causes the sun’s apparent eastward motion among the stars in the background. This is how the Sun ‘reaches’ a celestial coordinate, how it ‘crosses’ the boundaries between constellations, or how it is ‘in’ a constellation.

   With respect to the southern hemisphere this is the end of their summer and start of their fall season. So thinking globally my preference has been to use the name of the month to designate the season change. Hence the use of the term June Solstice rather than summer solstice.

Moon Near Aldebaran

Thursday morning August 25th watch for the last quarter Moon to be either close to the star Aldebaran or occulting Aldebaran – depending on your location. This occultation will be visible from around Hawaii across the Pacific Ocean toward the southern United States of America and Estados Unidos de Mexico.
   Aldebaran is the reddish and brightest star in the constellation of Taurus the Bull and from mythology Aldebaran represents the angry eye of the bull. Aldebaran is also part of the v-shaped group of stars forming the face of the bull, and this group of stars, the Hyades, is also an open star cluster – a group of stars clustered together by their respective gravitational forces. The Pleiades, looking like a small dipper, is another nearby open star cluster and part of the Taurus constellation.

June Solstice 2016

21june-ecliptic   Northern hemisphere spring comes to an end and its summer begins on Monday June 20th at 22:34 UT (5:34 pm CDT) when the Sun ‘reaches’ the celestial coordinates of 23.5o north declination and 6 hours right ascension. With respect to the Earth’s surface the Sun is described as over the Tropic of Cancer, 23.5o, north latitude of the Earth’s equator. At this same time the Sun is still within the boundaries of the constellation Taurus the Bull – but just barely. Interestingly about 8 hours later, June 21st at 8 UT (3 am CDT) the Sun ‘will move’ into the region of Gemini as it crosses the boundary between Gemini and Taurus.
   According to the pseudoscience of astrology the Sun, at this date, would be entering the astrological sign of Cancer the Crab.

Sun Enters Taurus

view-from-earth-may
   Friday May 13th the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Aries the Ram and into the constellation of Taurus the Bull. 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.
