Core Viewpoint - The last total lunar eclipse of the year will occur from the night of September 7 to the early morning of September 8, 2023, and it will be the only fully visible lunar eclipse in China this year, making it a highly anticipated astronomical event [1]. Group 1 - The initial phase of the lunar eclipse will begin at 0:27 AM Beijing time on September 8, with the penumbral phase lasting approximately 3.5 hours, making it a significant celestial event worth waiting for [4]. - The phenomenon of the "Blood Moon" occurs during a total lunar eclipse when the Earth blocks all sunlight from reaching the moon, causing the moon to appear red due to the scattering of sunlight by the Earth's atmosphere [6]. - The intensity and color of the "Blood Moon" can vary, and a French astronomer introduced the "Danjon scale" to classify the brightness and color of the moon during the eclipse into five levels, influenced by factors such as the moon's path through the Earth's shadow and atmospheric conditions [10]. Group 2 - A lesser-known phenomenon during the lunar eclipse is the "Turquoise Band," which occurs when the ozone in the upper stratosphere absorbs red light, creating a blue edge around the Earth's red shadow. Observers are encouraged to use high-magnification telescopes to capture this effect [13]. - Observing a lunar eclipse from the moon would present a "total solar eclipse plus," as the Earth would completely block the sun, creating a unique visual experience with a red halo around the Earth's edge [13].
