Moon Conjunction with Aldebaran

   Tuesday evening, November 10th, about an hour or so after sunset, the 14.5-day old waxing gibbous Moon will be about 2-3o from the reddish star Aldebaran. Aldebaran is at one end of the v-shaped open star cluster the Hyades in Taurus the Bull.

November Moon at Descending Node

   Yesterday Friday November 29th the Moon crossed the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic. For those keeping count this is the 2nd descending node crossing for the Moon this month.

Thin Moon – 2 Days – 2 Conjunctions

   At around sunset Thursday November 28th look toward the western horizon for the 2.5-day old thin waxing crescent Moon to be close to the inner planet Venus, and an outer planet, Jupiter. The Moon will be about 1-2o from Venus and about 6o from Jupiter.
   Too dim to be seen with the naked eye at 8-9th magnitude and about 3o from the Moon is the Dwarf Planet Ceres.
   The planet Saturn is about 12o to the east from the Moon – which is where the Moon will be on the evening of November 29th. The two will be about 1-2o from one another.

   Both of these conjunctions between the Moon and planets are tight enough such that both groupings will easily fit within the field of view of binoculars.

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.

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*
