The ONU Observatory will have a public star party to celebrate the autumnal equinox, the astronomical start of fall. Viewing will take place from 8-10 p.m. on Friday. The observatory is located on West Lincoln Street near Klingler Road.
On this day, which can also land on early Sept 23, the Earth's equatorial plane intersects the Sun. Consequently, we experience approximately equal durations of nighttime and daytime ("equi-nox" means equal night).
Also, the Sun rises due East and sets due West on this day. The telescopes will be targeting the setting Moon, Saturn, Uranus, and deep sky objects.
