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.

November Moon at Ascending Node

   Tuesday November 27th 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 the day of the node crossing the 20-day old waning gibbous Moon will be about 5o from the open star cluster known as the ‘Beehive Cluster’, M-44. Given that the Moon has an apparent magnitude of -12.0 compared with the 4th magnitude of the Beehive Cluster it may be difficult to see the star cluster.

   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*

November Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit on Monday November 26th. At that time the Moon will be at a distance of 28.74 Earth diameters 227,809 miles (366,623 km) from the Earth.

   The 18-day old Waning gibbous rises after sunset and is visible all night between the Gemini Twin stars and the bright star Capella in Canis Minor. Off to the east is the inner planet Venus shining brightly with an apparent magnitude of -4.6, and within about 4o from the blue-white star Spica (0.9 apparent magnitude) in Virgo the Harvest Maiden. About 10o east from Venus is the closest Dwarf Planet, Ceres. With an apparent magnitude of 8.0 Ceres is not visible to the unaided eye.

Taurus Takes it on the Nose!

    Friday evening October 26th the 18-day old waning gibbous Moon will be 5-6o from the reddish star Aldebaran. This star, at the point of the v-shaped open star cluster the Hyades, represents an angry eye of Taurus the Bull.

Moon – Mars Conjunction


   Sunday July 1st the 17-day old waning gibbous Moon will be within about 4o from Mars as the two rise in the east around midnight local time. Rising ahead of the Moon and Mars and further west are two of the four ringed planets, Saturn and Jupiter.
