Eunike Daily Motion
Eunike rise at 16:45, and will be at 20° when twilight starts at 18:41. It will reach its transit at 37° at 21:55, and will set at 03:06, before twighlight ends at 03:23.185 Eunike will be visible until January, 22, when it will move too close to the Sun.

The graph illustrates the annual visibility pattern of a Eunike, 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 Eunike 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.
