Moon and Saturn Conjunction


   Tuesday morning February 21st the 23.5-day old waning crescent Moon will be 4-5o away from the planet Saturn as this graphic shows. With 7×50 binoculars the two should make for a striking pair.

February Perigee Moon

6feb-perigee_moon   The Moon reaches perigee, (minimum distance from Earth), this month on Monday February 6th. At that time the Moon will more or less be at a distance of 28.91 Earth diameters (368,816 km or 229,172 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 perigee Moon 13-day old nearly full Moon rises just before sunset local time and is located near the feet of the Gemini Twins.
   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 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.

Moon Near Jupiter and Spica


   Thursday January 19th morning several hours before sunrise local time the last quarter Moon will be within a few degrees from Jupiter and the blue-white star Spica in Virgo the Harvest Maiden.
This graphic simulates a view using 10×50 binoculars.

January Moon at Ascending Node

15jan-ascending-node   Sunday January 15th 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 January 15th the 16-day old waning gibbous Moon will come within about 1o from the star Regulus in Leo the Lion.

   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*

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.
8jan-bino  Through 7×50 binoculars the stars of the open star cluster the Hyades and the Moon will make for an interesting sight.
