Moon Passes Spica

   Shortly after midnight local time on January 26th-27th the 20-21 day old waning gibbous Moon will pass within 10-11o from the blue-white star Spica. This star marks a bundle of wheat in the left hand of Virgo the Harvest Maiden.

Moon – Regulus Conjunction

   Tuesday evening January 22rd the 17-day old waning gibbous Moon will be about 2o from the heart of the ‘Lion’, the star Regulus in the constellation Leo the Lion. Regulus marks the bottom of the backward question mark shape of the head and chest of the Lion.

    Both the Moon and Regulus will easily fit within the field of view of binoculars.

January Moon at Perigee

click on graphic to see it larger   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Monday January 21st. At that time the Moon will be at a distance of 28.015 Earth diameters 357,345 km (222,044 miles) from the Earth.

   The 16-day old Waning gibbous Moon rises shortly after sunset local time is visible all night. Over the southwestern horizon, as the Moon is rising,is the planet Mars which sets around midnight.

   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 and the Hyades

   Wednesday and Thursday January 16th and the 17th the waning gibbous Moon will be passing past the open star cluster the Hyades and the reddish star Aldebaran. This is a v-shaped group of stars that make up the face of Taurus the Bull. The Hyades is one of two open star clusters in the constellation Taurus. The other is a small dipper-shaped group of stars, the Pleiades, located on the shoulder of Taurus.

Christmas Morning with the ISS and the Moon

   Happy Holidays.
    This was the sky this morning with the International Space Station passing from west to the northeast and along the way passing my chimney and the North Star. The ISS, as it was rising, passed near the waning gibbous Moon, as the Moon was setting. However, the camera was aimed toward the North Star away from the Moon as the ISS past by the Moon.

December Moon at Perigee and Ascending Node

   Our Moon reaches perigee, (closest distance to Earth), for this orbit on Monday December 24th. At that time the Moon will be at a distance of 28.30 Earth diameters 224,352 miles (361,060 km) from the Earth.

   Monday December 24th 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 Monday December 24th the 18-day old waning gibbous Moon rises around 7:30 pm local time.
