[:ja]クリスティーナ・コッシュ宇宙飛行士がISSから撮影した月の動きです。ISSからは1日に16回月の入りと出が見られますが、この動画のように、ISSの位置によっては月が地球に沈まず、もう一度上がってきます。
Moon chasing. Usually we see 16 moonsets & moonrises a day, but every so often our orbit happens to be right over the day/night line on Earth & the moon & sun never appear to set. Add in a partial lunar eclipse and the #Apollo50th Anniversary, & it’s a magical time to moon gaze. pic.twitter.com/6PckPsVPyO

[Earthview Wonders] No.816: Moon Chase
Astronaut Christina Koch captured from ISS the movement of the Moon. ISS spots 16 moonsets and moonrises a day, but sometimes does it spot Moon not completely setting behind the Earth as ISS happens to be on the day/night line.
