Sun Does Not Enter Gemini

  According to the pseudoscience of astrology the Sun enters the constellation of the Gemini Twins on Tuesday May 21st. When in fact the actual position of the Sun on this date is still within the boundary of the constellation of Taurus the Bull, as this graphic and the banner graphic show.

   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 Superior Conjunction

orbital-positions   Tuesday May 21st the innermost planet Mercury reaches superior conjunction. At superior conjunction Mercury will be on the opposite side of the Sun. The graphic to the right shows the planet positions relative to the Earth and Sun for both inner planets and outer planets.

   While at this superior conjunction Mercury will not be directly in line with the Earth and the Sun – on the ecliptic. Mercury has an orbital inclination of 7o with respect to the ecliptic. So like our Moon, Mercury during each complete orbit, will cross the plane of the ecliptic moving north (ascending node) and also moving south (descending node). For this superior conjunction Mercury had just crossed the ecliptic moving north.

Sun Enters Taurus

   Tuesday May 14th 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.

A Tale of Two Phases

   Over the next couple of weeks the two inner planets, Mercury and Venus, will be above the eastern horizon in the hour or two before the Sun rises. Given its much brighter apparent magnitude (-3.92) Venus will be more noticeable. However Mercury (0.03) is only a few degrees away, down to the left as they both rise. This graphic shows the two planets (sizes greatly enlarged for the graphic) and their respective orbital paths. Both planets are moving eastward toward the Sun and will eventually catch up with and move to the opposite side of the Sun, behind the Sun as we view from Earth to their respective superior conjunction.

   As these two planet orbit toward the Sun they pass through phase changes much like our Moon. Currently both planets are waxing gibbous but as they move into superior conjunction they will be at full phase. But unlike our Moon at full phase the inner planets are not visible at their respective full phase. When they do reappear on the east side of the Sun they will be again at gibbous phase, and will be following the Sun across the sky, setting after the Sun as an ‘evening planet’.

Sun Not in Taurus

April 19th  According to the pseudoscience of astrology the Sun enters the constellation of Taurus the Bull on Saturday April 20th. 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 19th.

Sunspot on the Move

   The Sun is now displaying a rather large sunspot. It started appearing April 8th, and the following morning the sunspot was even more obvious. These pictures were taken with a Cannon Rebel EOS T7i with a Thousand Oaks Optical Solar Filter. This type of filter is a ‘visible light’ solar filter that makes it safe to look at, and take pictures of the Sun. In order to see flares, prominences and other features typically shown in solar images requires special filters. Among the more popular for ‘amateur use is a Hydrogen-alpha filter telescope.
    Camera settings for all pictures: 300 mm; f/32;/ ISO-6400; 1/60 sec .
