For Northern Hemisphere observers Jupiter was visible at sunset for the first week of December. But then it becomes lost to view on December 27th as it reaches solar conjunction. "Solar conjunction" is when the Sun is directly in between Earth and another planet. The planet Jupiter will be passing on the far side of the Sun as seen from the Earth, called conjunction. Because Jupiter orbits outside of the orbit of Earth, it will be shifting from the evening sky to the morning sky and will begin emerging from the glow of dawn on the eastern horizon in January 2020. Since last May, Jupiter has been a fixture of the evening sky, shining more brightly than anything other than Venus, Moon and the rising sun itself. Not anymore. The third planet is swinging behind the sun and getting lost in the glare. Human eyes can't see it, but coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) can: For approximately the next two weeks, Jupiter will be a bright dot in daily SOHO coronagraph images, moving from left to right. SOHO will be able to track Jupiter as it passes by the sun, transitioning from an evening planet in 2019 to a morning planet in 2020. Solar conjunction, when Jupiter is almost directly behind the sun, occurs on Dec. 27, 2019. Join SOHO for a ringside seat.
