Each row is the satellite's next visible pass — visible means the satellite is sunlit while your sky is dark, peaking at least 10° up. The soonest of these passes gets its own chart below. Orbital elements refresh from CelesTrak every few hours.

The dashed curve is the moon’s path, its rise, set and highest point marked with times; the 00 and 24 dots are the moon’s positions at the day’s two midnights — the curve is open between them because a lunar day runs about 50 minutes longer than a calendar day, and near full moon that break sits right at the top of the arc. The bands below the horizon line are civil, nautical and astronomical twilight depth.
