Thin Crescent Moon Conjunction with Jupiter

   Thursday morning January 3rd the 27.25-day old thin waning crescent Moon will be within 3-4o from the outer planet Jupiter. The two will easily within the field of view of binoculars. Jupiter is about 5-6o from the heart of Scorpius the Scorpion, the reddish star Antares.

Saturn at 2018 Solar Conjunction

10dec-saturn-solar-conjunction   Wednesday January 2nd the planet Saturn will have reached the astronomical coordinates that officially place it at solar conjunction. From our perspective the planet is behind the Sun, or on the opposite side of the Sun from the Earth.
   In reality it is not as much as Saturn moving behind the Sun as it is the Sun passing in front of Saturn – or so it seems. As a distant outer planet Saturn moves more slowly around the Sun than the Earth does. One year on Saturn is equal to 29.7 years (10,832 days) on Earth. So in one day Saturn would travel how much of the 360o orbit around the Sun? That would amount to approximately 0.033o each day.
   The Sun, in its apparent motion along the ecliptic moves at the rate the Earth is moving which is 0.99o each day. So with the Sun’s apparent motion (0.99o/day) it quickly, relative to Saturn, passes Saturn while both are moving eastward. So with that in mind you could start watching for Saturn to reappear in the morning skies later next month.

A Trio of Pairs

   Sunday morning December 30th the 23-day old waning crescent Moon (apparent magnitude -11.76) will be 5-6o from the blue-white star Spica in the constellation of Virgo the Harvest Maiden. Both the Moon and Spica (apparent magnitude 0.96) will fit within the field of view of 7×50 binoculars.

   Rising about an hour after the Moon and Spica is another pair of celestial objects, the hard to miss Venus (apparent magnitude -4.48) is within 2-3o from the Dwarf Planet Ceres (apparent magnitude 8.0). Both of these will easily fit within the field of view of 7×50 binoculars.

   
   
   
   
   
   Wait about an hour, depending on your eastern horizon, and the planet Jupiter (apparent magnitude -1.8) will be about 5-6o from the reddish star Antares (apparent magnitude 1.0) in the constellation of Scorpius the Scorpion. And they will be high enough above the horizon to be more visible. Both Jupiter and Antares will fit within the field of view of binoculars.

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.
