    "editorial_note_md": "A rare sky event occurred on October 14 as Io passed in front of Callisto, occulting it from our view. This event is of interest to sky-watchers because it allows them to observe the unique alignment of Jupiter's moons. Observers in the US Midwest and farther west had a great opportunity to witness this event, and those who missed it can look forward to similar alignments in the future.
