Taurus Sniffs the Moon!

   Saturday evening November 2nd the 14.5-day old waxing gibbous Moon (full Moon tomorrow) will be a couple of degrees from the reddish star Aldebaran in Taurus the Bull. Aldebaran is at one end of a v-shaped open star cluster, the Hyades, that makes up the face of Taurus. Because of its reddish color it has been described as the angry eye of the bull.
   Normally the Hyades are a great view with binoculars as is the Pleiades, another open star cluster that is often described as a ‘baby dipper’.

October Moon at Descending Node, Again


   Sunday October 29th 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 10-day old waxing gibbous Moon will be over the southern horizon an hour or so after sunset local time. The Moon will be about 10o from the outermost, and 8th, planet Neptune.

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 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 2nd Apogee

   For the second time this month our Moon reaches apogee, (greatest distance from Earth), on Wednesday August 30th. At that time the Moon will more or less be at a distance of 31.69 Earth diameters (404,308 km or 251,225 miles) from the Earth.

   On the day of the apogee the 10-day old waxing gibbous Moon rises during mid-afternoon and is about 7o from Saturn and around 10o degrees from the reddish star Antares in Scorpius the Scorpion.

   Does our Moon actually go around the Earth as the above 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*

August Moon at Apogee

   Our Moon reaches apogee, (greatest distance from Earth), on Wednesday August 2nd. At that time the Moon will more or less be at a distance of 31.75 Earth diameters (405,934 km or 252,857 miles) from the Earth.
   On the day of the apogee Moon the 11-day old waxing gibbous phase, rises mid-afternoon and is about 3o from Saturn and around 14-15o degrees from the reddish star Antares in Scorpius the Scorpion. The Moon and Saturn will fit easily within the field of view binoculars.

Moon Passes Antares and Saturn

   Welcome to August!
   Over the next few days the Moon will wax from first quarter on Sunday July 30th into its waxing gibbous phases prior to reaching full Moon on August 7th. During this time, Tuesday August 1st to Thursday August 3rd, the Moon will first pass the reddish star Antares in Scorpius the Scorpion then the next day pass the outer planet Saturn on the 2nd. The following day has the Moon about mid-way across the Milky Way as the picture shows, however given the Moon’s bright reflected light it would be nearly impossible to see the Milky Way.
