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.

March Perigee Moon

   The Moon reaches perigee, (minimum distance from Earth), this month on Monday March 26th. At that time the Moon will more or less be at a distance of 28.90 Earth diameters (369,106 km or 229352 miles) from the Earth.
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*

On the day of perigee the 9.5-day old waxing gibbous Moon rises at mid-afternoon and is located between Procyon in Canis Minor and Regulus in Leo the Lion.

Moon – Regulus Conjunction


   Wednesday evening February 28th the nearly full Moon will be within 1-2o from the star Regulus in Leo the Lion.
   Given how close the two will be offers an opportunity to photograph both, or at least enjoy the view through the eyepiece of your choice.

January Moon at Ascending Node

   Thursday January 4th the waning gibbous Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   On Thursday January 4th the 17-day old waning gibbous Moon will be within the boundaries of Leo the Lion and about 11o west from the ‘Heart’ of the Lion, the star Regulus.
   While you are outside looking at the Moon turn toward the eastern horizon to see the planets Jupiter and Mars.
This animated graphic is set for 6 am CST (12 UT).

December Moon at Ascending Node

   Friday December 8th the waning gibbous Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.


   On December 8th the 21-day old waning gibbous Moon will be within the boundaries of Leo the Lion and about 3o east from the ‘Heart’ of the Lion, the star Regulus.

Moon-Regulus Conjunction


   Saturday morning November 11th the 23-day old waning crescent Moon will be about 0.5o from Regulus, the ‘heart’ of Leo the Lion. Both will fit comfortably within the field of view of binoculars.
