Top: image art002e009301 captured by the Artemis II crew during their lunar flyby at an altitude of approximately 6545 km above the lunar surface. The Moon fully occults the Sun, and the left side of the lunar disk is illuminated by sunlight reflected from the Earth. The apparent lunar diameter is 16﹩\mathop{.}\limits^{\unicode{x000b0}}﹩9. The glowing halo around the dark lunar disk corresponds to the F-corona (inner zodiacal light), and numerous stars are visible in the surrounding field. Bottom: the same image with an overlaid ecliptic coordinate grid. The yellow marker indicates the position of the Sun, which has an apparent diameter of ﹩31.^{\prime} 9﹩ and is located behind the Moon.
