This page describes a video Jupiter, Io and its shadow, by Ralf Burkart, Germany
Video caption:
First place in the 2021 IAU OAE Astrophotography Contest, category Galilean moons.
This time-lapse of Jupiter taken in 2017 from Germany beautifully illustrates the transit of one of the Galilean moons, Io, in front of Jupiter. As this is simply a moon casting a shadow on a planet it is equivalent to a lunar eclipse on Earth observed from further away. While the shadow of the moon is clearly visible from the beginning, it might be difficult to spot the moon itself against the background of the beautiful atmospheric bands of Jupiter the first time the video is seen. Watching it repeatedly allows appreciating the rapid motion and rotation in this fantastic observation.

Video caption: Primo posto al concorso di astrofotografia IAU OAE 2021, categoria Lune Galileiane.
Questo time-lapse di Giove ripreso nel 2017 dalla Germania illustra splendidamente il transito di una delle lune galileiane, Io, davanti a Giove. Trattandosi semplicemente di una luna che proietta un'ombra su un pianeta, è equivalente a un'eclissi lunare sulla Terra osservata da più lontano. Mentre l'ombra della luna è chiaramente visibile fin dall'inizio, potrebbe essere difficile individuare la luna stessa sullo sfondo delle bellissime bande atmosferiche di Giove la prima volta che si guarda il video. Guardarlo ripetutamente permette di apprezzare il rapido movimento e la rotazione in questa fantastica osservazione.
