November Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Saturday November 23rd. At that time the Moon will be at a distance of 28.75 Earth diameters, 227,870 miles (366,721 km) from the Earth.

   On the day of the perigee Moon the 26-day old very thin waning crescent Moon will be over the eastern horizon rising within about 6-7o from the blue-white star Spica in the constellation Virgo the Harvest Maiden.

   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*

A Pair of Conjunctions

   Sunday November 24th there will a photo or viewing opportunity during the twilight hour before the Sun rises and after the sun has set. Starting off the day will be a conjunction involving the very thin waning crescent Moon near the ‘Red Planet’ Mars. The two will be separated by about 3-4o. Lower or to the east is the innermost planet Mercury.
   Then, approximately 12 hours later, the Sun has or is about to set and over the western horizon is a cluster of 3 planets. Close together and separated by about 1-2o are the planets Jupiter and Venus. Higher or to the east is the planet Saturn.
    Both of these conjunctions will look great through binoculars or a wide-field eyepiece on a telescope, and obviously will make for interesting pictures.

Sun Does Enter Scorpius

   Saturday November 23rd the Sun, in its apparent eastward motion along the ecliptic, moves out of the constellation Libra the Scales and into the constellation of Scorpius the Scorpion. 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.

Sun Does Not Enter Sagittarius

  According to the pseudoscience of astrology the Sun enters the constellation of Sagittarius the Archer on Friday November 22nd. When in fact the actual position of the Sun is still within the boundaries of the constellation of Libra the Scales. And 2-3 days later the Sun will have entered the Astronomical constellation of Scorpius the Scorpion.

Moon – Regulus Conjunction

   Wednesday morning November 20th watch for the 3rd quarter Moon to be about 5-6o to the east from the heart of Leo the Lion, the star Regulus. This graphic shows the skies at 1:00 am CST – my time zone, and is great for those up late or cannot sleep!
   However a more reasonable time for seeing this conjunction may be a few hours later as the Sun rises.

The Leonids Peak and the Moon May Get Stung!

   Sunday night November 17th the 21-day old waning gibbous Moon will pass by the open star cluster M-44, aka the Beehive Cluster. M-44 is a group of stars, an Open Star Cluster, approximately 160 light years distant, within the constellation of Cancer the Crab. Actually seeing the stars in M-44 may not be possible due to the difference in the apparent magnitude of the Moon (-12.4) and the Beehive Cluster (3.4).
   Over the hours when the Moon is above the horizon it will pass by the Beehive Cluster. From some locations you may be able to see the Moon eclipse some of the stars.

   The Leonid Meteor Shower reaches its peak at 6 UT November 18th which for the U.S.A. Central Time Zone (UT-6) the peak is at 12:00 am CST, (just after 11:59 pm CST on the 17th). This means that for my location Leo and the meteor radiant rise around midnight. And then after the meteor radiant and the constellation are above the horizon the reflected sunlight from the Moon will brighten the sky making it difficult to see any but the very brightest meteors.

November Moon at Ascending Node

   Late in the evening of Saturday night November 16th the 20-day old waning gibbous Moon rises. As it is rising the Moon will be crossing the plane of the ecliptic moving north. 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 the day of the node crossing the waning gibbous Moon will be about 7o from the star Pollux in the constellation of the Gemini Twins.

   Does our Moon actually go around the Earth as many graphics show? 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*
