Moon Near Saturn


   Sunday morning, April 16th the 19-day old waning gibbous Moon will rise near the planet Saturn. The two will be within the 7o field of view of 10×50 binoculars and will be easily seen over the eastern to southeastern horizon in the hours before the sun rises.

Duck! Said Scorpius to Sagittarius

   Over the next several mornings, before the Sun rises, the Moon, as it wanes from gibbous to last quarter phase, glides past the stars of Scorpius the Scorpion and Sagittarius the Archer and the ringed planet Saturn.
   Apparently Archery is so loud that Sagittarius didn’t hear the warning and gets a face full of the Moon on the 21st.
   In the background is the Milky Way, but for the most part it will be difficult to see due to the bright reflected light from the Moon.
   Off to the west is Jupiter and Spica. Jupiter has been in retrograde motion since last month and is gradually moving west away from Spica.

March Moon at Apogee

 Our Moon reaches apogee, (greatest distance from Earth), on Saturday March 18th. At that time the Moon will more or less be at a distance of 31.72 Earth diameters (404,640 km or 251,432 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 morning of the apogee Moon the 20-day old waning gibbous Moon rises a couple of hours before the Sun and is visible over the southern horizon.

Moon Near Jupiter and Spica


   Tuesday evening March 14th look for the waning gibbous Moon to be about 5-6o from the giant planet Jupiter and the blue-white star Spica. Both of which are within the constellation of Virgo the Harvest Maiden. The trio will make for an interesting view with binoculars.

The Moon, Jupiter, and Spica – Together Again


   Wednesday February 15th the 18-day old waning gibbous Moon will be within a few degrees from the planet Jupiter and the blue-white star Spica in Virgo the Harvest Maiden as they rise in the east a few hours before sunrise local time.
   All three will fit within the field of view of a pair of 7×50 binoculars as this graphic shows.

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*

December Moon at Ascending Node

19dec-ascending-node   Monday December 19th 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 the morning of the 19ththe 20-day old waning gibbous Moon will be over the south-southwest horizon and will not set until close to 12 pm local time, after having risen during mid-evening local time the night before. The Moon is below Leo the Lion and above one of the longest, if not the longest, constellation. This is Hydra the many headed snake.
