Asteroid 89 Julia Observation Details
Julia Daily Motion
Julia will rise before twilight begins, at 21:59, and will reach 9° elevation by the time twilight commences at 22:48. It will reach its transit at 37° by 03:11 and gradually fade away as the night ends at 04:28, maintaining an elevation of around 34°.89 Julia will be visible until February, 14, 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.

The graph illustrates the annual visibility pattern of a Julia, providing a comprehensive overview of its daily appearances and transit times throughout the year.
The graph is structured with the vertical axis showing the hours of the day, ranging from 12 AM to 12 AM the next day, while the horizontal axis spans each day of the year.
The reddish shaded area indicates the periods when the Julia is above the horizon, visible to observers. The white line marks the times when the celestial object reaches its highest point in the sky each day, known as the transit.
