Moon Cruises Past Planets and Stars

feb5-bino
   Over the next several evenings the Moon, as it orbits toward the east and waxes from crescent to first quarter phase will pass by several planets, dwarf planets, and star clusters. On the evening of February 5th the Moon will be close to the reddish star Aldebaran, the ‘eye’ in the face of the angry bull, Taurus. This should make for a nice view with binoculars or low power eyepiece when the Moon will sort of overlay the stars of the open star cluster the Hyades.

   These two animated graphics show the sky as viewed from Quito Ecuador at 0o latitude, and my home latitude of approximately 40o North. They show the sky at one day intervals starting with February 1st and ending with February 5th.

Moon Gets Nosed by the Bull

   Sunday January 8th the 11 day old waxing gibbous Moon will be a few degrees from the nose of Taurus the Bull, and the stars making up the open star cluster the Hyades.

Full Moon – Spoiler Alert!

   Wednesday December 14th the Moon will be at its full phase and while pleasing to observe the reflected light from the Moon plus any local light pollution spoils the night sky as either one or both brightens the night sky making it difficult to impossible to see much of anything except the very brightest of celestial objects. What this brighter sky means in terms of December 14th is that the nearby open star cluster M-35 will not be seen, nor will the Geminids Meteor Shower with a radiant near the Moon and which peaks on the 14th.

December Perigee Moon Hits the Bull’s Eye

14dec-perigee_moon   The Moon reaches perigee, (minimum distance from Earth), this month on Monday December 12th. At that time the Moon will more or less be at a distance of 28.1 Earth diameters (356,509 km or 221,524 miles) from the Earth.
   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*
   On the day of the lunar perigee the 13.5-day old waxing gibbous Moon rises at around sunset local time and is over the southwest horizon at sunrise the following morning. The Moon is also very close to the star Aldebaran in the v-shaped open star cluster making the face of Taurus the Bull, the Hyades. Depending on your location this may be an occultation of the star by the Moon, or a very close conjunction. Nonetheless with binoculars or a wide field telescope eyepiece the Moon superimposed on the Hyades should make for great viewing.

Moon Near a Beehive


   Very early Sunday morning October 23rd the 22-day old last quarter Moon will be a few degrees from the open star cluster M-44, or commonly known as the ‘Beehive Cluster‘. This should make for an interesting sight with binoculars despite the reflected light from the Moon.

   If you are not a late night observer but like me an early morning observer then the Moon will still be close to M-44 before sunrise. However at that time look south-southeast and high above the horizon. To the right is Procyon in Canis Minor and above the Moon are the ‘Twins’ Pollux and Castor.

Moon in the Bull’s Eye

   Tuesday night and Wednesday morning October 18th and 19th the 18-day old waning gibbous Moon will be close to the eye of Taurus the Bull, the reddish star Aldebaran. From other locations the Moon will pass in front, occult, Aldebaran. The path for seeing the occultation stretches from Central America, Mexico, parts of eastern U.S.A., eastern Canada and then curves south toward northwestern Africa. The occultation is calculated to begin at 7 UT on Wednesday October 19th.

   Through binoculars the Moon, Aldebaran, and the stars making up the v-shaped face of Taurus, the Hyades, should all fit comfortably within the 7o field of view of 7×50 binoculars.

Moon May Get Stung!

   Monday morning September 26th the 25-day old waning crescent Moon will be within about 5o from the open star cluster M-44, also known as the Beehive Cluster. This is a collection of several hundred stars with a combined apparent magnitude of around 4 making it bright enough to be seen with the unaided eye.

   Even in moderately light polluted skies M-44 can be seen, and seen even better when viewed with binoculars.
