Abstract: The Moon-based Extreme Ultraviolet Camera (EUVC) aboard China’s Chang’e-3 (CE-3) mission has successfully imaged the entire Earth’s plasmasphere for the first time from the side views on lunar surface. An EUVC image on 21 April 2014 is used in this study to demonstrate the characteristics and configurations of the Moon-based EUV imaging and to illustrate the determination algorithm of the plasmapause locations on the magnetic equator. The plasmapause locations determined from all the availabl…
