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.

Moon – Regulus Conjunction


   Sunday morning October 15th the 25-day old waning crescent Moon will be less than 0.5o from the star Regulus in Leo the Lion. This should make for a great view with binoculars or a low-power telescope eyepiece.

Dance of the Planets – 20 Sep. Venus / Regulus Conjunction

   This morning the inner planet Venus and the ‘heart of the lion’, the star Regulus were about 0.5o from each other. Lower near the horizon and emerging from the mornning cloud layer is the other inner planet Mercury, and just above and fainter the planet Mars.
