Sun Actually Not in Leo


   According to the pseudoscience of astrology, Wednesday July 22rd the sun will be entering the constellation of Leo the Lion. In fact the Sun is still within the boundaries of the constellation Cancer the Crab, having just entered that region two days ago.
   The difference between the two locations of the Sun, the correct astronomical vs. the incorrect astrological, is due to the effects of precession, or more specifically, the precession of the Earth’s axis. The Earth wobbles on its axis like a spinning top does as the top slows down. So, in approximately 26,000 years the Earth will have spun, or wobbled one time. This is a repetitive cycle and over the course of one precession cycle the poles of the Earth trace out a circle against the background stars over their respective pole. any star on or nearest to this precession circle is the pole star. Currently the north pole of the Earth points toward Polaris and within this century, due to precession, will point the closest it will be, and then over time the Earth’s north pole will shift away.
   Another effect of precession has been to cause the celestial grid system to shift moving the original signs of the zodiac by at least one constellation to the west. In other words the Sun is more to the east which in effect means that whatever your zodiacal sign may be according to astrology, you are really the constellation to the west, or before it according to Astronomy.

   The Science of Astronomy has its roots in astrology with the origins of astrology beginning several millennia ago possibly by the Babylonians. Regardless of its origins the basis for at least Sun astrology, the popularized version printed in newspapers, is the position of the Sun relative to stars in the background. However we now know that due to the effects of precession the Sun’s position is no longer as it was during the beginnings of astrology.
    The slideshow below shows the sun’s position within Cancer on July 22nd 2016 AD, and then shifts to show the sun in Leo 4,000 years ago on 22 July 2016 BC. Precession has shifted the sun’s position one constellation to the west.

June Solstice – 2020

   Northern hemisphere spring comes to an end and its summer begins on Saturday June 20st at 21:45 UT (4:45 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 according to astrology the Sun is said to be entering the boundaries of the astrological constellation Cancer the Crab. Actually it is not. Interestingly about 7 hours later, June 21st at 9 UT (4 am CDT) the Sun will actually be entering the region of the Gemini Twins as it crosses the boundary between Gemini and Taurus.

   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.

Sun Not Really In Cancer

   According to the pseudoscience of astrology the Sun enters the constellation of Cancer the Crab on Sunday June 21st at 9 UT (4 am CDT). When in fact the actual position of the Sun on this date is still within the boundary of the constellation of Taurus the Bull, but by very little. The Sun is very close to the eastern boundary for Taurus and the western boundary for the Gemini Twins, as this graphic and the banner graphic at the top of the page shows.
   Interestingly the June solstice was yesterday

Say it Ain’t So!


   According to the web site Physics-Astronomy on May 16th the crescent Moon will be in a conjunction with the inner planet Venus and an outer planet, Jupiter, in a formation looking like a smiley face.

   This type of conjunction has happened in the past including one in 2 B.C. that has been suggested to be the ‘Star of Bethlehem’. More recently this triple conjunction did happen in December 2008, according to the article.
   Click here to see a list of future planetary conjunctions.

   Looking down from above the solar system on May 16th showing the orbital positions of Venus, the Earth, and Jupiter. From this graphic it shows that from the Earth you would have to look toward different directions to see either planet.

   No this will not happen.
   Here are reasons why this article about the conjunction is “fake news”.

   Venus is visible in the evening skies at sunset over the western horizon and sets around 9-10 pm local time. (Rises: 7:23 am – Sets: 10:24 pm)
   Jupiter is visible in the morning skies over the southern horizon and sets during the afternoon local time. (Rises: 12:45 am – Sets: 10:47 am)
   The article does not indicate which crescent Moon. Is this a waxing crescent Moon in the evening or a waning crescent Moon in the morning?
   The Moon is in fact a 22.8-day old waning crescent Moon in the morning skies. However the Moon is closer to Neptune and Dwarf Planet Ceres than it is to either Venus or Jupiter.

Sun Enters Taurus the Bull – 2020

   Wednesday 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.

Sun Not In Taurus – 2020

April 19th  According to the pseudoscience of astrology the Sun enters the constellation of Taurus the Bull on Sunday April 19th. When in fact the actual position of the Sun on the 19th is within the boundary of the constellation of Aries the Ram, as this graphic shows. Actually the Sun had just entered Aries the day before on April 18th.

March Equinox – 2020

   Friday March 20th, this year-2020, is an equinox day. However depending on your local time zone the equinox may occur on the day before as the official time for the equinox is 03:54 UT on the 20th which for my time zone is 10:54 pm March 19th. Regardless, for those in the northern hemisphere winter is ending and spring has ‘sprung’ (starts). From a geographical perspective we would describe the Sun as being over the Earth’s equator, and as this graphic shows there would be an equal amount of daylight and night on our planet as a result.
    At mid-day on the equator the sun is directly overhead and from that latitude you have no elongated shadow, just a ‘blob-like’ shadow at your feet as this picture of my feet taken at mid-day in Quito Ecuador shows.

    Regardless of your hemispheric preference get outside and cast a shadow!

  Northern hemisphere spring officially (well at least astronomically) begins at 03:54 UT on the 20th which for my time zone is 10:54 pm March 19th when the Sun reaches the celestial coordinates of 0 hours and 0 degrees as it moves northward along the ecliptic crossing the celestial equator. At this location the Sun is just within the constellation of Pisces the Fishes and not entering Aries the Ram as the pseudoscience of astrology would have you believe.

   During a trip to Quito Ecuador to visit one of the exchange student we had hosted, and her family, we spent the day at a Museum on the equator, Mitad del Mundo. I brought along my over-sized protractor knowing in advance that we would be at the museum. So at mid-day I had my wife stand on the equator (yellow line) and hold a string to the top of her head while Cathy, a sister of our exchange student, held the protractor. This was done during the summer so the Sun was over the northern horizon at mid-day and the Sun’s angle above the northern horizon was around 75o.

   Here is a short series of hourly pictures taken during the day on the September equinox on the equator in Quito Ecuador at Collegio Menor San Francisco de Quito, a private school that I visited and did the SunShIP project with (Sun Shadow Investigation Project).

Sun Enters Capricornus not Aquarius- – 2019


 Monday January 20th at 9 UT the Sun in its apparent eastward motion along the ecliptic enters the boundaries of the constellation Capricornus the Sea Goat. This is the actual location of the Sun.
   Interestingly, according to the pseudoscience of astrology, 6 hours later, at 15 UT Monday January 20th, the Sun should be entering the constellation of Aquarius the Water Bearer.

Friday December 13th 2019

Heidi

Heidi the 13th

   Friday December 13th is Friday the 13th! The number 13 is considered to be bad luck, as is any Friday occurring on a day number that is 13. Neither of which should portend bad things… however!
   For those that keep count, every year will have at least one Friday the 13th, while some years, like this one, have two Friday the 13th. Very interestingly the previous one was 13 weeks ago on – yes, wait for it… in September on Friday the 13th!
   Last year there were three of these days, but on the average those years only happen about 15 times each century. What is kind of interesting is that there are more Friday the 13th days than any other day of the week on a 13th. It is also thought that the Friday the 13th is more or less a modern thing as there seem to be no records or very few accounts of the idea of a Friday the 13th until sometime early during the last century.

   For those that like words, a fear of Friday the 13th is called friggatriskaidekaphobia, while a fear of the number 13 is called triskaidekaphobia.
