Asteroid 40 Harmonia Observation Details
Harmonia Daily Motion
Harmonia will be visible throughout the entire night. It will rise at 14:12, just before twilight begins, and will be at 28° when twilight starts at 16:40. It will reach its transit at 77° at 21:31, and will fade away as twilight ends at 03:49, being at 11° elevation.40 Harmonia will be visible until May, 31, 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 Harmonia, 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 Harmonia 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.
