September 14-lunar occultation

"For outer planets such as Jupiter, because of their long orbital period around the sun and very far away from the earth, the moving speed on the stellar background is relatively slow, and Jupiter still needs 5 to 6 years to move to the upper and middle heaven and earth. Near the Taurus and Gemini with a higher level.
Jupiter is the largest planet in the solar system. Jupiter revolves around the sun on the outer side of the earth, and there is an opposition opportunity every 400±1 days. That is, it rises from the east after sunset and is visible all night. At this time, the observation time is the longest and it is the closest to the earth, which is a good opportunity for observation. At this time, Jupiter is far brighter than usual, and is clearly visible to the naked eye. For about 20 days before and after the Opposition, Jupiter rises over the eastern horizon in the early evening, just as the sun sets, and does not set in the west until sunrise the next day at a magnitude of -2.6. Therefore, astronomers can clearly see the "biggest of the eight planets" shining in the constellation Ophiuchus with the naked eye all night long.

At opposition, the celestial body is visible all night, at its brightest, and the planet appears as a complete circle. Conjunction means that the ecliptic longitudes of two celestial bodies are the same, and when viewed from the earth, the two celestial bodies are in the same direction"
