Asteroid 110 Lydia Observation Details

Lydia

Lydia Daily Motion

Lydia will rise before twilight begins, at 20:02, and will reach 4° elevation by the time twilight commences at 20:19. It will reach its transit at 70° by 02:01 and gradually fade away as the night ends at 05:50, maintaining an elevation of around 30°.
110 Lydia will be visible until February, 2, when it will move too close to the Sun. During this time, its proximity to the Sun will cause it to disappear from the night sky, making it unobservable for a while.
