Venus – Mars Conjunction


   Thursday morning October 5th the inner planet Venus will be within about 0.5o from the planet Mars. With either a telescope or through binoculars the two planets will make for a great view.

October Moon at Descending Node

   Monday October 2nd the waxing gibbous Moon will be crossing 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.
   

   On the day of the node crossing the 13-day old waxing gibbous Moon will be over the east-southeast horizon an hour or so after sunset local time. The Moon will be about 10o from the outermost, and 8th, planet Neptune.

September Moon at Ascending Node

   Sunday September 17th the waning crescent 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 September 17th the thin 26.5-day old waning crescent Moon will be within the constellation of Leo the Lion. The Moon will be located about 6o from Venus, and about 9o from the heart of the Lion, the star Regulus. A few more degrees further east from Venus and Regulus (below, as they rise in the morning), is the ‘Red Planet’ Mars, and nearby is the innermost planet Mercury.
   These two planets are close enough for both to be seen in the field of view of binoculars.

   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*

September Moon at Descending Node

   Monday September 4th the waning gibbous Moon will be crossing 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.
   

   On the day of the node crossing the 14-day old waxing gibbous Moon will be over the east-southeast horizon an hour or so after sunset local time. The Moon will be about 10o from the outermost, and 8th, planet Neptune.

August Moon at Ascending Node – and Oh Yeah, A Total Solar Eclipse!

   Monday August 21st the new 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 August 21st the new Moon will be crossing the plane of the ecliptic at 10:34 UT (5:34 am CDT) within the constellation Leo the Lion. 8 hours later, at 18:30 UT (1:30 pm CDT), the Moon will reach new phase. This close timing between the new Moon phase and a node crossing means only one thing – eclipse!!

   My eclipse viewing area will be at an Elementary School in the North Kansas City School District. From that location totality will be approximately 80 seconds. This short video showing totality for 80 seconds, was clipped and edited from a video shot during the November 2012 total solar eclipse viewed from Australia.

   Read a bit more about this eclipse from a previous post.

Taurus Head-Butts the Moon


   Wednesday morning August 16th the 24-day old waning crescent Moon is within 2-3o from the reddish star Aldebaran and the rest of the stars of the open star cluster the Hyades, forming the v-shaped face of Taurus the Bull.

   
   
   With 10×50 binoculars the Hyades and the Moon will all fit within the field of view as this graphic is showing.

Triangulating with the Moon

   Tuesday morning, August 15th the 23-day old first quarter Moon will be the point of a celestial triangle with the two open star clusters, the Pleiades, and the Hyades as this graphic shows. The v-shaped Hyades forms the face of Taurus the Bull while the ‘dipper-shaped’ Pleiades lies along the Bull’s shoulder. Both open star clusters are about 8o from the Moon.
