October Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Saturday October 26rd. At that time the Moon will be at a distance of 28.75 Earth diameters, 224,511 miles (361,316 km) from the Earth.

   On the day of the perigee Moon the 27.5-day old very thin waning crescent Moon will be over the eastern horizon rising within about 5-6o from the planet Mars. Both will be rising about 1 hour before the Sun so it may be difficult to see them.
   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*

Sun Not in Scorpius – 2019

  According to the pseudoscience of astrology the Sun enters the constellation of Scorpio the Scorpion on Wednesday October 23rd. When in fact the actual position of the Sun is still within the boundaries of the constellation of Virgo the Harvest Maiden.
   Before the Sun rises on Wednesday morning watch for the 24-day old waning crescent Moon to be 4-5o from the ‘heart’ of Leo the lion, the star Regulus.

   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.

Waning Crescent Moon Near the Beehive Cluster

  If you are an early riser, on Tuesday morning October 22nd before the Sun rises, look for the 23-day old waning crescent Moon to be about 3-4o from the open star cluster M-44, also known as the Beehive Cluster. This is a group of around 1000 stars estimated to around 500-600 light years distant.
   The two will fit within the field of view of binoculars however the Moon has an apparent magnitude of -12 compared to the 3.5 apparent magnitude of the Beehive Cluster so it will be a challenge to see it near the much brighter Moon.

Moon in Close Conjunction with Jupiter

   Wednesday evening October 3rd the 5-day old waxing crescent Moon will be about 1-2o from -2 magnitude Jupiter. Should make for a great view using binoculars. Keep an eye on the Moon over the next few days as it continues moving eastward and waxing toward first quarter phase and the planet Saturn.

September Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Saturday September 28th. At that time the Moon will be at a distance of 28.05 Earth diameters, 222,328 miles (357,803 km) from the Earth.

   On the day of the perigee Moon the 29-day old very thin waning crescent Moon will be over the eastern horizon rising within about 30 minutes ahead of the Sun. This puts the Moon too close to the Sun to be seen. The waning crescent Moon becomes new Moon about 12 hours after the Sun and Moon rise.

   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*

Moon – Regulus Conjunction

   Thursday morning September 26th, before the Sun rises, watch for a thin 27-day old waning crescent Moon to be about 2-3o from the ‘heart of Leo the lion, the star Regulus.

   Both Regulus and the Moon will easily fit within the field of view of binoculars, and the pair should make an interesting comparison of apparent magnitudes. The waning crescent Moon with a -10.0 apparent magnitude and Regulus with 1.34 apparent magnitude.

Moon Near Beehive Cluster

   Tuesday morning before the Sun rises the 26-day old waning crescent Moon will be about 6>sup>o from the open star cluster M-44, or more commonly known as the ‘Beehive Cluster’, or from the Latin for manger or cradle, Praesepe. M-44 is a group of approximately 1,000 stars at a distance of around 600 light years.

   The open star cluster covers about 1-2o and is easily seen in dark skies with the unaided eyes as a fuzzy patch of light. Through binoculars or with a low power wide field telescope eyepiece M-44 resolves to individual stars.
