Core Points - The article discusses the lunar occultation of the Pleiades star cluster, providing an opportunity for public observation on November 6 [1][4]. Group 1: Pleiades Star Cluster - The Pleiades star cluster, located in Taurus, is one of the closest and brightest open star clusters, typically visible to the naked eye with six to seven bright stars [2]. - The confirmed number of stars in the Pleiades cluster exceeds one thousand [2]. Group 2: Lunar Occultation Events - The moon's orbit around the Earth, known as the ecliptic, allows for multiple lunar occultations of the Pleiades throughout the year, with four notable occurrences in 2023 [4]. - The specific dates for observable lunar occultations in 2023 are March 5, August 16, November 6, and December 31 [4]. Group 3: Observational Conditions - The visibility of the Pleiades during the lunar occultation is affected by the moon's phase, with smaller moon phases providing better visibility of the stars [8]. - On November 6, the moon will rise above the Pleiades, starting to obscure it around 10 PM, with the event lasting approximately two hours [8].

Core Points - The "lowest full moon" of the year will occur on June 11, 2023, providing a unique astronomical event for the public in the Northern Hemisphere [1] - The phenomenon is explained by the moon's orbit around the Earth, which changes its position in the sky, leading to varying appearances of the full moon [4] - The full moon on June 11 corresponds to the lunar date of the 16th day of the fifth month, occurring at 15:44 Beijing time, with the moon being approximately 400,000 kilometers away from Earth [6] Group 1 - The term "lowest full moon" refers to the full moon that occurs when the moon is at its lowest declination in the sky, which happens when the moon's position aligns with the full moon phase [4] - The full moon's timing is influenced by the lunar calendar, with the specific date of June 11 being significant for its low position in the sky [6] - The moon's declination will reach its lowest point at -28 degrees 24 minutes on June 12, making the June 11 full moon particularly notable [6] Group 2 - The relationship between the sun, earth, and moon creates an average angle of 5 degrees 9 minutes between the moon's orbit and the earth's orbit, affecting the visibility of the full moon [9] - The lowest full moon typically occurs in summer due to the inverse relationship between the sun's and full moon's declination heights [11] - This year's "lowest full moon" is particularly rare as it approaches the minimum value of the moon's declination, resulting in a visually striking appearance from the Northern Hemisphere [9]
