Fall Equinox Begins Wednesday

 Fall Equinox Begins Wednesday

This week’s Harvest Moon, other nighttime wonders are just a telescope away

The autumnal/fall equinox—or the beginning of fall—officially occurs at 3:20 p.m. Eastern Daylight Time Wednesday in the Northern Hemisphere. The sun will be directly above the equator, and day and night hours are roughly equal. The Harvest Moon is the full moon nearest the fall equinox. The moon was at its fullest Monday, but it will continue to be bright in the nights ahead. Now is a good time to get acquainted with the Cincinnati Observatory.

The Cincinnati Observatory, 3489 Observatory Place in Hyde Park, offers many in-person and virtual astronomical educational events for children and adults, as well as viewings of the night sky. The Observatory, known as “The Birthplace of American Astronomy,” was dedicated in 1843 in a ceremony overseen by former President John Quincy Adams, who gave his last public speech there. Its main telescopes are an 11-inch Merz and Mahler refractor from 1845 and a 16-inch Alvan Clark and Sons refractor from 1904.
