Moon in Conjunction with Regulus

   Thursday morning November 29th the 22-day old waning gibbous Moon will be 1-2o from the heart of Leo the Lion, the star Regulus. By sunrise the Moon and Regulus will be over the southern horizon. At about that time Venus, shining very brightly, is still close to Spica as the two rise a couple of hours before the Sun rises.
   This is also the time of the year when the winter circle of constellations (Taurus, Auriga, Gemini Twins, Canis Minor, Canis Major, and Orion) start showing up over the horizon during the late evening hours.

October Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit on Friday October 5th. At that time the Moon will be at a distance of 28.72 Earth diameters (227,668 miles (366,396 km) from the Earth.

   Friday morning October 5th the very thin 25-day old waning crescent Moon will be about 4-5o from the star Regulus in Leo the Lion.

   Does our Moon actually go around the Earth as this graphic shows? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

Mercury Passes the Heart of the Lion


   Early mornings this week, before the local time of sunrise, look toward the east for the innermost planet Mercury as it moves east passing within about 1-2o from the star Regulus. This animated graphic shows the morning skies on September 5th to the 7th at 5:15 am CDT

   
   
   
   Regulus marks the bottom of the backward question shape for Leo the Lion, and Regulus also represents the heart of Leo.

Sun Enters Leo

10aug-view_from-earth
   Friday August 10th the Sun in its apparent eastward motion along the ecliptic, moves out of the constellation Cancer the Crab and into the constellation of Leo the Lion. 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.

   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.

Moon in Conjunction with Venus


   Sunday evening July 15th the 3-day young waxing crescent Moon will be 2o from Venus, and 5o from the star Regulus in Leo the Lion. Further to the east are the planets Jupiter, Saturn, and Mars.


   The three, Moon, Venus, and Regulus, all fit comfortably within a binocular field of view.

Moon Near Heart of the Lion

   Sunday evening the 4.3-day old waxing crescent Moon will be about 4o from the star Regulus, the heart of Leo the Lion. Spread across the sky from west to east are three planets, Venus, Jupiter, and Saturn.

Venus and Moon Are In Conjunctions

   Monday evening May 21st the first quarter Moon and the inner planet Venus will each be in their own respective conjunctions. Venus is within 1o from the open star cluster, M-35, located near the foot of Castor, one of the Gemini Twins. Venus currently shines with an apparent magnitude of -3.96, and at that brightness will outshine the 5th magnitude of M-35.

    Nonetheless the two should be visible with binoculars, as this graphic simulates, as well as a couple of 3rd magnitude stars nearby.


   Further toward the east, and unmistakable is the first quarter Moon. During the night hours the Moon, as it orbits eastward, will pass within about 1.5o from the star Regulus in Leo the Lion. Since Regulus is very close to the ecliptic there is a good chance that the Moon and Regulus will have a regular repetitive pattern or cycle of conjunctions. As in the months that Regulus is above the horizon, which include the next two months, June 18th and July 15th.
